Description:

The Factorial function is great, if you want to know the value of 5!. But what if the value you’re given is 120, and you want to know which factorial would give you that product? Enter Arcfactorial.

This function has been tested to FileMaker’s indexable limits of Factorial ( 212 ), but like FileMaker’s own Factorial function, does not handle half-factorials.

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