				1596	Say Y here to include the FAST floating point emulator in the kernel.
				1597	This is an experimental much faster emulator which now also has full
				1598	precision for the mantissa. It does not support any exceptions.
				1599	It is very simple, and approximately 3-6 times faster than NWFPE.
				1600
				1601	It should be sufficient for most programs. It may be not suitable
				1602	for scientific calculations, but you have to check this for yourself.
				1603	If you do not feel you need a faster FP emulation you should better
				1604	choose NWFPE.
