				1622	Say Y here to include the FAST floating point emulator in the kernel.
				1623	This is an experimental much faster emulator which now also has full
				1624	precision for the mantissa. It does not support any exceptions.
				1625	It is very simple, and approximately 3-6 times faster than NWFPE.
				1626
				1627	It should be sufficient for most programs. It may be not suitable
				1628	for scientific calculations, but you have to check this for yourself.

				1630	choose NWFPE.
