For those of us who, like me, forgot high school math, or who, like me, are totally not able to find an existing function to do this in FileMaker (probably because it can be done by combining existing functions)

I threw the rounding in there just because you don't always get an integer result when you supply integers as parameters (probably due to FM's finite definition of the constant "e")

EDIT: duh, this can be done with ^, as in 2^3 as pointed out in the comments below. Hopefully FMI will start giving awards for most pointless CFs...

Note: these functions are not guaranteed or supported by Please contact the individual developer with any questions or problems.

This is my Custom Function and I want to edit it


Hi Peter,

Haa haaa haaahhaaa! 8 years using FileMaker and it was right there under the "Not". Pays to scroll.... Thank you!

That's what I was going to say...


^ is listed as one of the operators in the calculation engine, it's just that you have to scroll down to find it.

I used it in a complicated amortization calculation and compared it to calcs in our existing application and it worked perfectly.

FYI - I don't believe that FMTouch supports the ^ operator so this might be a nice workaround.
