[geos-devel] NaN

[Paul Ramsey]

What is this about? Doesn't C++ have some standards for representing 
NaN, Inf, and -Inf?

  #ifndef GEOS_PLATFORM_H
  #define GEOS_PLATFORM_H
  //Defines NaN for intel platforms
  #define DoubleNotANumber 1.7e-308

  //Don't forget to define infinities
  #define DoubleInfinity 1.7e+308
  #define DoubleNegInfinity -1.7e+308

  #endif
