* Bitwise Functions and 32-bit
When running the test suite with 32-bit PHP, a failure was reported in BITLSHIFT.
In fact, all of the following are vulnerable to problems, and didn't report
any failures only because of a scarcity of tests:
- BITAND
- BITOR
- BITXOR
- BITRSHIFT
- BITLSHIFT
Those last 2 can be resolved fairly easily by using multiplication by a power of 2
rather than shifting. The first 3 are a tougher nut to crack, and I will continue
to think how they might best be approached. For now, I have added skippable tests
for each of them, which at least documents the problem.
Aside from adding many new tests, some bugs were correctd:
- The function list in Calculation.php pointed BITXOR to BITOR.
- All 5 functions allow null/false/true parameters.
- BIT*SHIFT shift amount must be numeric, can be negative, allows decimal portion
(which is truncated to integer), and has an absolute value limit of 53.
- Because BITRSHIFT allows negative shift amount, its result can overflow
(in which case return NAN).
- All 5 functions disallow negative parameters (except ...SHIFT second parameter).
This was coded, but the code had been thwarted by an earlier is_int test.
* Full Support for AND/OR/XOR on 32-bit
Previous version did not support operands 2**32 through 2**48.
* Merge branch 'master' of C:\Projects\PHPOffice\PHPSpreadsheet\develop with conflicts.
* Bessels, and set some date tests to defined/named arguments
* Fix test class naming
* Names arguments for math/trig tests
* Docblock updates
* More engineering function unit test refactorings
* More engineering function unit test refactorings. This time, moving on to the Complex engineering functions
* Fix ImConjugate test
* Fix parseComplex test
* Fix parseComplex test
* More of the complex number function unit tests refactored
* Finish refactoring of the complex number function unit tests
* Newer phpunit assertions
* Add parsecomplex unit test back until we're ready to drop the deprecated function; but as it doesn't use the specified data provider at all, drop reference to that
