				1608	Say Y here to include the FAST floating point emulator in the kernel.
				1609	This is an experimental much faster emulator which now also has full
				1610	precision for the mantissa. It does not support any exceptions.
				1611	It is very simple, and approximately 3-6 times faster than NWFPE.
				1612
				1613	It should be sufficient for most programs. It may be not suitable
				1614	for scientific calculations, but you have to check this for yourself.

				1616	choose NWFPE.
