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.public final class StrictMath {
