fabs, fabsf, fabsl -- floating-point absolute value functions
Math Library (libm, -lm)
#include <math.h>
double
fabs(double x);
float
fabsf(float x);
long double
fabsl(long double x);
The fabs(), the fabsf() and the fabsl() functions compute the absolute
value of a floating-point number x.
The fabs(), the fabsf() and the fabsl() functions return the absolute
value of x.
abs(3), ceil(3), floor(3), ieee(3), math(3), rint(3)
The fabs() function conforms to ISO/IEC 9899:1990 (``ISO C89''). The
fabsf() and the fabsl() functions conform to ISO/IEC 9899:1999
(``ISO C99'').
