Greetings, I’m working with a client making use of POI to do some heavy calculations of workbook formulas in java. We’re having issues with the precision of some of the math functions (TwoOperandNumericOperation) being based on double math rather than BigDecimal math. The issue isn’t with the precision of the input or return parameters being doubles, but with rounding / truncation / precision of the math functions.
If the OperationEvaluatorFactory had public methods for manipulating the OperationPtg -> Function map, I could swap in my own implementations that use BigDecimal and not need to worry about patching / forking POI to do it. Would exposing a way to manipulate that map via a public method in the OperationEvaluatorFactory be something I could get merged upstream? Regards, -Bryan Varner
