* Support 'Forms' for ROMAN Function
This seems like an exceptionally silly thing for MS to have implemented
(Wikipedia on Roman Numerals: "There is no indication this is anything
other than an invention by the programmer").
Nevertheless, we can, and therefore probably should, implement it.
Not that I can implement it by an algorithm - Excel describes the various extra
styles as "more concise", "more concise", "more concise", and "simplified".
Nevertheless, since the universe of potential calls is relatively small,
it can be implemented as a table of values where the new forms would return
a different value than "classic". This table is relatively large, so I have
put it its own member to avoid overhead when the function is needed.
* Move ROMAN To Its Own Class

* PHP 8.1 Deprecations
PHP8.1 Unit tests failed. 1 line fixes are available for
- Shared/Font
- Shared/XMLWriter
- Style/Color
- Writer/HTML
The problem is that an error is also reported for a strcmp at
line 272 of Cell/Cell. Not only does that line not invoke strcmp,
there is no strcmp in all of Cell/Cell, so I don't know what to make
of the error message. Oh well, let's fix what can be fixed.
Still dealing with the mysterious PHP8.1 unit test failure in Cell\Cell,
which seems to have something to do with strcmp. The only uses of
strcmp that I can find in src/ are in Calculation. I can't find any
use of it in test/ or samples/. So, if this doesn't fix the problem,
I may have to give up.
* ROUND Accepts null, false, and true as First Parameter
Issue #1789 was addressed by PR #1799. In a follow-up discussion,
it came to light that ROUND was not handling the unexpected case where the
first parameter is an empty cell in the same manner that Excel does.
Subsequent investigation showed that a boolean first parameter is permitted.
I broadened my investigation to include the following related functions.
- ROUNDUP
- ROUNDDOWN
- MROUND
- TRUNC
- INT
- FLOOR
- FLOOR.MATH
- FLOOR.PRECISE
- CEILING
- CEILING.MATH
- CEILING.PRECISE
All of these allow a NULL first parameter, and all except MROUND allow boolean.
For completeness, I will note that all treat null string as invalid.
I suspect there are other functions which permit
similarly unexpected parameters, but I consider them out of scope for this PR.
CEILING.MATH and CEILING.PRECISE were unimplemented, and are now supported
as part of this PR.
The tests for each of these functions have been re-coded, though all the original
test data is still included in the test cases, plus several new cases for each.
The new tests now take place as a user would invoke the functions,
through a spreadsheet cell rather than a
direct call to the appropriate function within Calculation/MathTrig.
Aside from being more realistic, the new tests are also more complete.
For example, FLOOR.MATH can take from 1-3 arguments, and the existing tests
confirmed that the function in Calculation could handle a single argument.
However, the function list in Calculation.php erroneously set the number of
arguments for FLOOR.MATH to exactly 3, so, if a user tried to get the calculated
result of a cell containing FLOOR.MATH(1.2), the result would be an Exception.
Aside from the parameter support, there are a few minor code changes.
Ods, as well as Gnumeric, allows the omission of the second parameter for
FLOAT and CEILING; Excel does not. A potential divide-by-zero error is
avoided in CEILING, FLOOR, and FLOORMATH.
I will note that it would probably be beneficial in terms of maintainability
to break MathTrig up into many individual modules. The same would hold for the
other Calculation modules. I would be willing to look into this if you agree
that it would be worthwhile.
* Extract DELTA() and GESTEP() functions from the Engineering class into a dedicated Comparison classes

* Additional unit tests for previously untested financial functions, and some additions to follow untested paths
* Start splitting Financial function tests out from the large FinancialTests class into individual test classes for each function
* Problems Using Builtin PHP Functions Directly As Excel Functions
This fixes issue #1789.
As originally reported, stricter typing was causing PHP8 to throw
an exception when a non-numeric value was passed to the Round function.
Previous releases of PHP did not see this problem, however, on further
analysis, they were also incorrect in returning 0 as the result in the
erroneous situation, when they should have been returning a VALUE error.
Yet more analysis showed that other functions would also have problems,
and, in addition, might not handle invalid input (e.g. a negative length
passed to REPT) or output (e.g. NAN in the case of ACOS(2)) correctly.
The following MathTrig functions are affected:
ABS, ACOS, ACOSH, ASIN, ASINH, ATAN, ATANH,
COS, COSH, DEGREES (rad2deg), EXP, LN (log), LOG10,
RADIANS (deg2rad), REPT (str_repeat), SIN, SINH, SQRT, TAN, TANH.
One TextData function (REPT) is also affected.
This change lets PhpSpreadsheet validate the input for each of these
functions before passing control to the builtin, and handle the output
afterwards.
There were no explicit tests for any of these functions, a fact made
easy to ignore by the fact that PhpSpreadsheet delegated the heavy
lifting to PHP itself for these cases. A full suite of tests is
now added for each of the affected functions.
* Scrutinizer Recommendations
Only in 3 modules which are part of this PR.
* Improved Handling of Tan(PI/2)

* Additional Trig Tests
Results which should be infinity, i.e. DIV/0 error.
Now supports all current UoM in all categories, with both 1- and 2-character multiplier prefixes, and binary multiplier prefixes, including the new Temperature scales
This had been intended to get 100% coverage for TextData functions, and it does that.
However, some minor bugs requiring source changes arose during testing.
- the Excel CHAR function restricts its argument to 1-255. PhpSpreadsheet CHARACTER
had been allowing 0+. Also, there is no need to test if iconv exists,
since it is part of Composer requirements.
- The DOLLAR function had been returning NUM for invalid arguments. Excel returns VALUE.
Also, negative amounts were not being handled correctly.
- The FIXEDFORMAT function had been returning NUM for invalid arguments. Excel FIXED returns VALUE.

Bugfix for negative results and too small results

For functions introduced in Excel 2010 and beyond, Excel saves them
in formulas with the xlfn_ prefix. PhpSpreadsheet does not do this;
as a result, when a spreadsheet so created is opened, the cells
which use the new functions display a #NAME? error.
This the cause of bug report 1246:
https://github.com/PHPOffice/PhpSpreadsheet/issues/1246
This change corrects that problem when the Xlsx writer encounters
a 2010+ formula for a cell or a conditional style. A new class
Writer/Xlsx/Xlfn, with 2 static methods,
is introduced to facilitate this change.
As part of the testing for this, I found some additional problems.
When an unknown function name is used, Excel generates a #NAME? error.
However, when an unknown function is used in PhpSpreadsheet:
- if there are no parameters, it returns #VALUE!, which is wrong
- if there are parameters, it throws an exception, which is horrible
Both of these situations will now return #NAME?
Tests have been added for these situations.
The MODE (and MODE.SNGL) function is not quite in alignment with Excel.
MODE(3, 3, 4, 4) returns 3 in both Excel and PhpSpreadsheet.
However, MODE(4, 3, 3, 4) returns 4 in Excel, but 3 in PhpSpreadsheet.
Both situations will now match Excel's result.
Also, Excel allows its parameters for MODE to be an array,
but PhpSpreadsheet did not; it now will.
There had not been any tests for MODE. Now there are.
The SHEET and SHEETS functions were introduced in Excel 2013,
but were not introduced in PhpSpreadsheet. They are now introduced
as DUMMY functions so that they can be parsed appropriately.
Finally, in common with the "rate" changes for which I am
creating a pull request at the same time as this one:
samples/Basic/13_CalculationCyclicFormulae
PhpUnit started reporting an error like "too much regression".
The test deals with an infinite cyclic formula, and allowed
the calculation engine to run for 100 cycles. The actual number of cycles
seems irrelevant for the purpose of this test. I changed it to 15,
and PhpUnit no longer complains.
There were about 20 skipped tests for RATE and PRICE marked
"This test should be fixed". This change does that by fixing
the code for those functions, validating the existing tests,
and adding new ones. XIRR and XNPV are also substantially changed.
As part of this change, the following functions also have minor changes:
- isValidFrequency
- COUPDAYBS
- COUPNUM (additional tests)
- DB
- DDB
PhpUnit reports 100% coverage for all the changed functions.
Since I was dealing with skipped tests, I also fixed
tests/PhpSpreadsheetTests/Writer/Xlsx/LocaleFloatsTest,
which was being skipped in Windows. I also delete the temporary
file which it creates.
There is now only one remaining test which is skipped -
ODS Reader is not complete enough to run some tests against it.
Unfortunately, that test is too complicated for me to deal with now.
In researching this change, I found several places in the code where special code was added for Gnumeric claiming:
- Gnumeric does not handle free-format string dates
- Gnumeric adds extra options, not available in Excel,
for the frequency parameter for functions such as YIELD
- Gnumeric rounds the results for DB and DDB to 2 decimal places
None of these claims is true, at least not on a recent version
of Gnumeric, and the code which supports these differences is removed.
There did not appear to be any tests targeted for
these supposed properties of Gnumeric.
The PRICE function needed relatively minor changes - mostly
additional tests for invalid input. The main problem with the PRICE
tests is that Excel appears to have a bug. The algorithm is published:
https://support.office.com/en-us/article/price-function-3ea9deac-8dfa-436f-a7c8-17ea02c21b0a
The results that Excel returns for basis codes 2 and 3 appear to be
incorrect in many cases. I have segregated these tests into a
new test PRICE3. The results of these tests agree with the published
algorithm, and to the results for LibreOffice and Gnumeric.
The results returned by Excel do not agree with them.
The tests which remain in the test PRICE all use basis codes other
than 2 or 3, and all agree with Excel, LibreOffice, and Gnumeric.
For the RATE function, there appears to be a problem with how the
secant method was implemented. I studied the implementation of RATE
in Python numpy, and adapted its implementation of secant method.
The results now agree with numpy, and, more important, with Excel.
XIRR, which calls XNPV, permits its dates to be earlier than the
start date, whereas XNPV does not. I dealt with this by renaming
the existing XNPV function to xnpvOrdered, adding a parameter to
indicate whether start date has to be earliest. XNPV calls the new
function with that parameter set to TRUE, and XIRR calls it with
the parameter set to FALSE. Some additional error checking was
added to xnpvOrdered, and also to XIRR. XIRR tests benefited
from increasing the value of FINANCIAL_MAX_ITERATIONS.
Finally, since this change is very test-related:
samples/Basic/13_CalculationCyclicFormulae
PhpUnit started reporting an error like "too much regression".
The test deals with an infinite cyclic formula, and allowed
the calculation engine to run for 100 cycles. The actual number of cycles
seems irrelevant for the purpose of this test. I changed it to 15,
and PhpUnit no longer complains.
Returns #N/A, unless the element searched for is at the end of the array.
The problem is in Calculation.php line 4231:
if (!is_array($functionCall)) {
foreach ($args as &$arg) {
$arg = Functions::flattenSingleValue($arg);
}
unset($arg);
}
I believe this code is intended to handle functions where PhpSpreadsheet just passes
the call on to PHP without implementing the code on its own, e.g. for atan or acos.
In the bug report, the following code fails:
$flat_rate = "=MATCH(6,{4,5,6,2}, 0)";
$sheet->getCell('A1')->setValue($flat_rate);
The expected value is 3, but the actual result is "#N/A".
The reason for this result is that the parser replaces the braces with calls
to the MKMATRIX internal function, whose value for functioncall was:
'self::MKMATRIX'. Since this isn't an array, the flattening code is executed,
and the unintended result occurs. The fix is to change the definition for
functioncall in that case to [__CLASS__, 'mkMatrix'], avoiding the flattening.
However, there is also another part to this bug. The flattening should be
returning the first entry in the array, but is in fact returning the last.
This explains why the bug report specified "unless ... end of the array".
I confirmed that Excel does use the first item in the array rather than the last,
e.g. =atan({1,2,3}) entered into a cell will return atan(1), not atan(3).
The problem here is that flattenSingleValue, which says in its comments that
it is supposed to be returning the first item, uses array_pop rather than array_shift.
I have changed that as well. The same mistake was also present in
Cell.php function getCalculatedValue. The correct behavior can be verified
by entering =minverse({-2.5,1.5;2,-1}) into an Excel cell'
Excel flattens the result ({2,3;4,5}) to 2, and so should PhpSpreadsheet.

* Changes to WEEKNUM and YEARFRAC
The optional second parameter for WEEKNUM can take any of 10 values
(1, 2, 11-17, and 21), but currently only 1 and 2 are supported.
This change adds support for the other 8 possibilities.
YEARFRAC in Excel does not require that end date be before start date,
but PhpSpreadsheet was returning an error in that situation.
YEARFRAC third parameter (method) of 1 was not correctly implemented.
I was able to find a description of the algorithm, and documented
that location in the code, and implemented according to that spec.
PHPExcel had a (failing) test to assert the result of
YEARFRAC("1960-12-19", "2008-06-28", 1). This test had been dropped
from PhpSpreadsheet, and is now restored; several new tests have
been added, and verified against Excel.
* Add YEARFRAC Tests
Scrutinizer reported a very mysterious failure with no details.
project.metric_change("scrutinizer.test_coverage", < 0),
without even a link to explain what it is reporting.
It is possible that it was a complaint about code coverage.
If so, I have added some tests which will, I hope, eliminate the problem.

In cells with formulas containing conditions like `=IFSUM(A1:A3;"";B1:B3)`
to sum cells from range A1:A3 with empty value in range B1:B3, the function
`Functions::ifCondition()` create in this case the code `=""""` instead of
`=""`, so it didn't work.

Calculation engine was resolving every function by first resolving its arguments
including IFs, this was causing significant over evaluation when IFs were used
as it meant for every case to be evaluated.
Introduce elements to identify ifs and enable better branch resolution
(pruning). We tag parsed tokens to associate a branch identifier to them.

Conditional operators in the selection parameter of COUNTIF
functions were not being parsed properly, causing evaluations
of formulae with such functions to sometimes fail.
Fixes#526Closes#528
This change adds support for newer functions that are prefixed
by _xlfn. (#356). The calculation engine has been updated to
recognise these as functions, and drop the _xlfn. part.
It also add a couple of the new functions such as STDEV.S/P,
MODE.SNGL, ISFORMULA.
Fixes#356Closes#390
By design, UTF-8 allows any byte-oriented substring searching algorithm,
since the sequence of bytes for a character cannot occur anywhere else
([source](https://en.wikipedia.org/wiki/UTF-8#Advantages_3)).
So `str_replace()` also works for UTF-8-encoded strings, assuming that
the input strings are valid UTF-8 strings. The previous implementation
of mbStrReplace() did nothing to detect invalid strings.
Also, `str_replace()` does not support [Unicode equivalence](https://en.wikipedia.org/wiki/Unicode_equivalence),
but nor do the other `mb_string` functions, and nor does `=SUBSTITUTE()` in Excel
(tested on Excel for Mac version 15.19.1, Excel 2016 for Windows and LibreOffice 5.1).
Closes#109
If $a or $b are not strings, you can get an error that fmod needs param 1 ($a) to be of type double.
MS Excel does not fall over when you insert an empty string in MOD, so I'm guessing PHPExcel should do the same?
