NAME

hypot, cabs, fabs − Euclidean distance calculation and complex absolute value

LIBRARY

Math Library (libm.a)

SYNOPSIS

#include <math.h>

double hypot  (double x, double y);
float  hypotf (float  x, float  y);
double cabs   (double x, double y);
float  cabsf  (float  x, float  y);
double fabs   (double x);
float  fabsf  (float  x);

DESCRIPTION

hypot() and hypotf() compute the length of the hypotenuse of a right triangle; where x and y represent the perpendicular sides of a right triangle.  hypot(x,y) and hypotf(x,y) are equivalent to sqrt(x∗∗2 + y∗∗2). 

cabs() and cabsf() return the complex absolute value of x and are equivalent to hypot() and hypotf(). 

fabs() and fabsf()  compute the absolute value of x.
