Detailed Description

Additional math routines for GeographicLib.

This defines constants:
  epsilon, difference between 1 and the next bigger number
  digits, the number of digits in the fraction of a real number
  minval, minimum normalized positive number
  maxval, maximum finite number
  nan, not a number
  inf, infinity
