SQRT()


Syntax:     SQRT(<expN>)

Purpose:    To return the square root of the specified numeric
            expression.

Argument:   <expN> is a numeric expression from which a square root
            is to be returned.  SQRT() operates on positive numbers
            only.

Returns:    A numeric value.

            The value returned by SQRT() is calculated to double
            precision.  The number of decimal places displayed is
            specified by SET DECIMALS regardless of SET FIXED.  A
            negative <expN> returns zero.
