This class is identical to the Math class, but additionally requires that its methods strictly adhere to the behavior of certain published algorithms. The methods of StrictMath are intended to operate identically on all platforms, and must produce exactly the same result (down to the very least significant bit) as certain well-known standard algorithms. When strict platform-independence of floating-point results is not required, use the Math class for better performance.
