Sqrt()

This function computes the square root of a number. It can operate on numeric, currency, integer and double values, but always returns a numeric value.

Usage

nResult = SQRT(nValue)

Since square roots aren't defined for negative numbers, VFP returns an error if you pass it a negative number.

Example

?SQRT(49)   && returns 7
?SQRT($81)  && returns 9
