FUNCTION
       <<fabs>>, <<fabsf>>---absolute value (magnitude)
INDEX
	fabs
INDEX
	fabsf

ANSI_SYNOPSIS
	#include <math.h>
       double fabs(double <[x]>);
       float fabsf(float <[x]>);

TRAD_SYNOPSIS
	#include <math.h>
       double fabs(<[x]>) 
       double <[x]>;

       float fabsf(<[x]>)
       float <[x]>;

DESCRIPTION
<<fabs>> and <<fabsf>> calculate 
@tex
$|x|$, 
@end tex
the absolute value (magnitude) of the argument <[x]>, by direct
manipulation of the bit representation of <[x]>.

RETURNS
The calculated value is returned.  No errors are detected.

PORTABILITY
<<fabs>> is ANSI.
<<fabsf>> is an extension.
