Description

Function Sqrt returns the square root of the specified value.

FUNCTION Sqrt(
        v   :REAL) : REAL;

def vs.Sqrt(v):
    return REAL

Parameters

v

REAL

Value for which to find the square root.

Remarks

Be aware that in VS, a number can be less than zero, even if it is equal to zero. The following script generates a "square root of a negative number" error...

PROCEDURE GenerateError;
VAR
temp_r :REAL;
BEGIN
temp_r := -.00000000000000000000000000000000000001;
IF temp_r = 0 THEN Message(sqrt(temp_r));
END;
RUN(GenerateError);
