MATH - declarations for mathematical functions.

Usage:

#include <math.h>

Description:

<math.h> declares the various mathematical routines in the C library:

double acos(double x);
double asin(double x);
double atan(double x);
double atan2(double y, double x);
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 value, int *exp);
double ldexp(double x, int exp);
double log(double x);
double log10(double x);
double modf(double value, double *iptr);
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);

<math.h> also #defines:

HUGE_VAL: the largest "double" value that can be defined on the machine.
