I apparently also replace a float->u16 function that uses float adds, sorry forgot about this. There's also some changes to the makefile in this. |

The define in math.h is probably also unnecessary, I'll remove it. |

Related to #39, #37 Can be disabled with a linker option if it causes issues. I removed the fdiv and fmul implementations again because they weren't that much faster than gcc's own in my tests, but there was a large difference for sqrtf, and I was able to match it the default implementation bit-for-bit just by adding rounding.
