* 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. |

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.
