[pure-lang-users] math.pure

[Eddie R. <er...@bm...>]

I got tired of importing math functions from the C library so I made a
wrapper for them.

If it sux just let me know and I'll try to make unsuck.

Notes
log b x - means log base b of x
ln x    - C's log x

I did not implement
 frexp - decomposes a number into scientific notation
 ldexp - computes a number in scientific notation
 modf  - decomposes a number into integer and fractional parts
 log10 - common logarithm (to base 10)
         Equivalent to log 10 x
