How to use GAMMA function _xlfn.GAMMA?












2















Microsoft website has an introduction on GAMMA function.



I could download it and have a look, it's a ".xlsx" file and the formula is shown as =_xlfn.GAMMA(2.5).



enter image description here



However, when I create a new excel ".xlsx" file, I can't use it, neither by write formula as =_xlfn.GAMMA(2.5)" or "=GAMMA(2.5).
enter image description here



Did I missed something? Is there some library I shall register, like using Solver function?





Clarification



@dave-rook is right.



I'm using Excel 2007. The msdn page says "GAMMA" function applies to Excel 2013, so the problem is the version.

  • youre right the function isnt included with the workbook. it does work on the embed spreadsheet on the web, but its not anywhere to find within the downloaded file itself.

In excel 2003 and up you can use



=EXP(GAMMALN(value))


For all positive values

    If GAMMALN is not available under your language settings, you may need to be using the following formula:



    =GAMMA.LN(EXP(value))
