CONFIG_FPE_FASTFPE: FastFPE math emulation (EXPERIMENTAL)

General informations

The Linux kernel configuration item CONFIG_FPE_FASTFPE:

Help text

Say Y here to include the FAST floating point emulator in the kernel. This is an experimental much faster emulator which now also has full precision for the mantissa. It does not support any exceptions. It is very simple, and approximately 3-6 times faster than NWFPE.

It should be sufficient for most programs. It may be not suitable for scientific calculations, but you have to check this for yourself. If you do not feel you need a faster FP emulation you should better choose NWFPE.
