Mark Baker c54e3e9979 Extract DELTA() and GESTEP() functions from the Engineering class into a dedicated Comparison classes (#1853) ... * Extract DELTA() and GESTEP() functions from the Engineering class into a dedicated Comparison classes Retain the original methods in the Engineering class as stubs for BC, but deprecate them. They will be removed for PHPSpreadsheet v2 Note that unit tests still point to the Engineering class stubs; these should be modified to use the Erf and ErfC classes directly when the stubs are removed		2021-02-13 20:52:20 +01:00
