		* Through the layoutlib_create tool, the original native methods of FloatMath have been replaced
		* by calls to methods of the same name in this delegate class.
		*
		* Math routines similar to those found in {@link java.lang.Math}. Performs
		* computations on {@code float} values directly without incurring the overhead
		* of conversions to and from {@code double}.
		* Because it's a stateless class to start with, there's no need to keep a {@link DelegateManager}
		* around to map int to instance of the delegate.
		*
		* <p>On one platform, {@code FloatMath.sqrt(100)} executes in one third of the
		* time required by {@code java.lang.Math.sqrt(100)}.</p>
