Function Sqrt() Foundation

Calculates square root of a positive number.

Syntax
Sqrt( <nValue> ) --> nSquareRoot
Parameters
<nValue>
<nValue> is a positive numeric expression whose square root is calculated.
Return

Sqrt() returns the square root as a numeric value. The number of decimal places displayed in the result depends only on the setting SET DECIMALS and not on SET FIXED. When the value of <nValue> is negative, zero is returned.

Description

Sqrt() is a mathematical function used in numeric calculation to determine the square root (for example in statistical evaluations calculating variances and standard deviations).
