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.
