Calculating square root of a number

I am trying to find out if there is a way to show to square root of a field in another field. I cannot find anything on these calculations anywhere.

I am trying to do this my self currently, did you ever figure it out? Thanks

The gform_calculation_result() filter has a JavaScript version (for showing the number on the front end) and a PHP version (to check that calculated value to see if it is consistent)

You must use both the PHP and the JavaScript versions of the filter.
