* Improve Coverage of BIN2DEC etc.
The following functions have some special handling
depending on the Calculation mode:
- BIN2DEC
- BIN2HEX
- BIN2OCT
- DEC2BIN
- DEC2HEX
- DEC2OCT
- HEX2BIN
- HEX2DEC
- HEX2OCT
- OCT2BIN
- OCT2DEC
- OCT2HEX
Ods accepts boolean for its numeric argument.
This had already been coded, but there were no tests for it.
Gnumeric allows the use of non-integer argument where Excel/Ods do not.
The existing code allowed this for certain functions but not for others.
Gnumeric consistently allows it, so there is no need for parameter
gnumericCheck in convertBase::ValidateValue.
Again, there were no tests for this.
There were some minor changes needed:
- In functions where you are allowed to specify the numnber of "places" in the
result, there is an upper bound of 10 which had not been enforced.
- Negative values were not handled correctly in some cases.
- There was at least one (avoidable) error on a 32-bit system.
- Some upper and lower bounds were not being enforced. In addition to enforcing
those, the bounds are now defined as class constants in ConvertDecimal.
Many tests have been added, so that Engineering is now almost 100% covered.
The exception is some BESSEL code. There have been some recent changes to
BESSEL which are not yet part of my fork, so I could not address those now.
However, I freely admit that, when I looked at the uncovered portion, it seemed
like it might be a difficult task, so I probably wouldn't have tackled it anyhow.
In particular, the uncovered code seemed to deal with very large numbers,
and, although PhpSpreadsheet and Excel both give very large results for these
conditions, their answers are not particularly close to each other. I think
we're dealing with resuts approaching infinity. More study is needed.
