NAME
fabsd64(), fabsd128(), fabsd32() - decimal absolute value functions
SYNOPSIS
#define __STDC_WANT_DEC_FP__
#include <math.h>
_Decimal64 fabsd64(_Decimal64 x);
_Decimal128 fabsd128(_Decimal128 x);
_Decimal32 fabsd32(_Decimal32 x);
DESCRIPTION
The fabsd64() function returns the absolute value of x,|x|.
fabsd128() is a _Decimal128 version of fabsd64(); it takes a
_Decimal128 argument and
returns a
_Decimal128 result.
fabsd32() is a _Decimal32 version of fabsd64(); it takes a
_Decimal32 argument and returns a
_Decimal32 result.
These math functions are supported for HP-UX 11i Version 3 September 2008 Update and forward.
USAGE
To use any of these functions, compile with the +decfp option.
Make sure your program defines
__STDC_WANT_DEC_FP__
and then includes <math.h>.
Link in the math library by specifying
-lm or -l:libm.a on the linking command line.

RETURN VALUE
fabsd64(±0) returns +0.
If x is ±infinity,
fabsd64() returns +infinity.
If x is NaN,
