Combines the magnitude of one number with the sign of another.
magnitude- The expression providing the magnitude of the result. Must be a numeric type.
sign-
The expression providing the sign of the result. Must be a numeric type.
Returns a value with the magnitude of the first argument and the sign of the second argument. This function is similar to Java's Math.copySign(double magnitude, double sign) which is similar to copysign from IEEE 754.
