Fast maths alternatives?

Hello,

I'm using fast-floats crate and works perfectly, but I would like to consult the community if they know of better alternatives, because I have seen that there are many options for this

Thank you !

Be warned that that crate is seemingly unsound; see Why I get NaN values when multiply by 0?.

There's probably no good option in safe code until rust gets to a newer version of LLVM.
