* 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.
PhpSpreadsheet
PhpSpreadsheet is a library written in pure PHP and offers a set of classes that allow you to read and write various spreadsheet file formats such as Excel and LibreOffice Calc.

PHPExcel vs PhpSpreadsheet ?
PhpSpreadsheet is the next version of PHPExcel. It breaks compatibility to dramatically improve the code base quality (namespaces, PSR compliance, use of latest PHP language features, etc.).
Because all efforts have shifted to PhpSpreadsheet, PHPExcel will no longer be maintained. All contributions for PHPExcel, patches and new features, should target PhpSpreadsheet master branch.
Do you need to migrate? There is an automated tool for that.
