Header:       math

Purpose:      Declares the mathematical functions and macros.

File:         math.h

Author:       K.G. Begeman

Use:          #include "math.h"

Declares:     double acos(double x);
              double asin(double x);
              double atan(double x);
              double atan2(double x, double y);
              double ceil(double x);
              double cos(double x);
              double cosh(double x);
              double exp(double x);
              double fabs(double x);
              double floor(double x);
              double fmod(double x, double y);
              double frexp(double x, int *exp);
              double ldexp(double x, int n);
              double log(double x);
              double log10(double x);
              double modf(double x, double *ip);
              double pow(double x, double y);
              double sin(double x);
              double sinh(double x);
              double sqrt(double x);
              double tan(double x);
              double tanh(double x);

Warning:      System dependent. At the moment implemented for ALLIANT,
              CONVEX, DEC ALPHA, DEC ULTRIX, HP 9000, IBM/RS6000,
              SILICON GRAPHICS, SUN and VMS.

Updates:      Apr 11, 1990: KGB, Document created.
              Jun  8, 2009: JPT, Linux now includes from system
