NAME
fmaxd64(), fmaxd128(), fmaxd32() - decimal maximum value functions
SYNOPSIS
#define __STDC_WANT_DEC_FP__
#include <math.h>
_Decimal64 fmaxd64(_Decimal64 x, _Decimal64 y);
_Decimal128 fmaxd128(_Decimal128 x, _Decimal128 y);
_Decimal32 fmaxd32(_Decimal32 x, _Decimal32 y);
DESCRIPTION
The fmaxd64() function determines the maximum numeric value of its arguments.
fmaxd128() is a _Decimal128 version of fmaxd64(); it takes
_Decimal128 arguments and
returns a
_Decimal128 result.
fmaxd32() is a _Decimal32 version of fmaxd64(); it takes
_Decimal32 arguments 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.
For more information, see the HP-UX floating-point guide for HP Integrity servers at the following site:

.
RETURN VALUE
If one argument is NaN and the other is numeric,
fmaxd64() returns the numeric argument.
If both arguments are NaN,
fmaxd64() returns NaN.
ERRORS
No errors are defined.
