| 912 | Say Y here to include the FAST floating point emulator in the kernel. |
| 913 | This is an experimental much faster emulator which now also has full |
| 914 | precision for the mantissa. It does not support any exceptions. |
| 915 | It is very simple, and approximately 3-6 times faster than NWFPE. |
| 916 | |
| 917 | It should be sufficient for most programs. It may be not suitable |
| 918 | for scientific calculations, but you have to check this for yourself. |
| 919 | If you do not feel you need a faster FP emulation you should better |
| 920 | choose NWFPE. |
