Mathf for doubles?

So im working with some fairly large doubles (upwards of 1+E20) and i was wondering if there are any Mathf libraries that use doubles? of if there's a workarround for this alternatively. i know unity can do normal maths with doubles just fine but the .NET mathf functions convert to a float first which breaks numbers above 1+E18.

specifically Mathf.Log() and Mathf.Ceil/Floor() in my case is what i need to be able to use

Im not really sure how to do those myself so i was hoping someone knew of a free library that would provide that functionality. or alternatively a place where i could learn to replicate the functions for my own use would actually be prefered.

 

NEVERMIND: >_> I FEEL SO DUMB!!!

so apparently .NET has built in math functions that use doubles instead of floats...referenced by Math.log() instead of Mathf.log()....welll...problem solved i guess XD

 

Yep, System.Math:

You may also be surprised to know that Mathf is really just a wrapper around System.Math that does the double to float conversion for you.
