Support for f64?

[ChristopherRabotin]

Hi there,

Is there any interest in supporting f64 in this crate? I am interested in converting a high precision scientific time computation library to no_std, but it requires 64-bit floating point values and a few functions (sin, div_euclid, and rem_euclid). I'd be happy to give it a shot.

Moreover, and maybe that should be a separate issue, using a Pade approximation for the cosine computation might increase the precision of the result if that is desired.

Cheers

Sure, that'd be great.

using a Pade approximation for the cosine computation might increase the precision of the result if that is desired.

If you'd like to attempt PoCing it, we can examine the precision/performance tradeoffs and determine if it's worth it.

However note that cosine is pretty much the core of the bulk of the trig functionality in this crate and the current approximation is highly optimized, albeit a bit lacking in precision.
