				1597	Say Y here to include the FAST floating point emulator in the kernel.
				1598	This is an experimental much faster emulator which now also has full
				1599	precision for the mantissa. It does not support any exceptions.
				1600	It is very simple, and approximately 3-6 times faster than NWFPE.
				1601
				1602	It should be sufficient for most programs. It may be not suitable
				1603	for scientific calculations, but you have to check this for yourself.
				1604	If you do not feel you need a faster FP emulation you should better
				1605	choose NWFPE.
