Approximate and vectorized versions of common mathematical functions

The easiest way to include this in your projects is via the one big standalone header file which works with both C and C++.

Current functions:

  • exponential, logarithm, and power
  • lgamma and digamma
  • cosh, sinh, tanh
  • cos, sin, tan
  • sigmoid and erf
  • Lambert W

There's a Mathematica notebook which helps explain the techniques.
