NAME
     fabs, fabsf, fabsl - absolute value function

SYNOPSIS
     c99 [ flag... ] file... -lm [ library... ]
     #include 

     double fabs(double x);


     float fabsf(float x);


     long double fabsl(long double x);


DESCRIPTION
     These functions compute the absolute value of x, |x|.

RETURN VALUES
     Upon successful completion, these functions return the abso-
     lute value of x.


     If x is NaN, a NaN is returned.


     If x is +_0, +0 is returned.


     If x is +_Inf, +Inf is returned.
