NAME
fmodd64(), fmodd128(), fmodd32() - decimal remainder functions
SYNOPSIS
#define __STDC_WANT_DEC_FP__
#include <math.h>
_Decimal64 fmodd64(_Decimal64 x, _Decimal64 y);
_Decimal128 fmodd128(_Decimal128 x, _Decimal128 y);
_Decimal32 fmodd32(_Decimal32 x, _Decimal32 y);
DESCRIPTION
The fmodd64() function determines the remainder ( f ) of the division of x by y, where f has the same
sign as x, such that x = iy + f for some integer i , and |f|<|y|.
fmodd128() is a _Decimal128 version of fmodd64(); it takes
_Decimal128 arguments and
returns a
_Decimal128 result.
fmodd32() is a _Decimal32 version of fmodd64(); 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.

.
RETURN VALUE
If y is ±infinity and x is not ±infinity,
fmodd64()
returns x.
If x is ±0 and y is a nonzero number,
fmodd64() returns x.
If y is 0,
fmodd64() returns NaN and raises the invalid exception.
If x is ±infinity,
fmodd64() returns NaN and raises the invalid exception.
If x or y is NaN,
fmodd64() returns NaN.
ERRORS
If x is ±infinity or y is 0,
fmodd64() sets errno to [EDOM].

STANDARDS CONFORMANCE
These functions conform to ISO/IEC TR 24732, "Extension for the programming language C to support
decimal floating-point arithmetic".
