A heterogeneous C library of interesting numeric functions

 This library provides:
  
   * a function for rounding floating point values to a specific number
     of digits
   * several pseudo-random number generators, including the Mersenne
     Twister, various algorithms by Marsaglia, and ISAAC
   * least common multiple and greatest common denominator functions
   * a few trigonometry functions for finding the inversions of hyperbolic
     sine, cosine, and tangent
  
 This library is also used by libevocosm, which is in turn the 
 foundation for Acovea, used to determine optimal compiler optimizations
