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);
