Created attachment 35091 [details] patch This method returns an int instead of an enum - some variants are marked for removal in 3.17 but not all. I'll attach a patch because I'd like to get a review before proceeding.
Changed method to return CellType and deprecated the getCachedFormulaResultTypeEnum method. https://svn.apache.org/repos/asf/poi/trunk@1808678
I resolved this as I think the main goal of having getCachedFormulaResultType return CellType is done, the deprecations will lead to removal in future versions anyway.
