fmodd32(), fmodd64(), fmodd128() — Calculate floating-point remainder

Standards

Format

#define __STDC_WANT_DEC_FP__
#include <math.h>

_Decimal32  fmodd32(_Decimal32 x, _Decimal32 y); 
_Decimal64  fmodd64(_Decimal64 x, _Decimal64 y); 
_Decimal128 fmodd128(_Decimal128 x, _Decimal128 y); 

_Decimal32  fmod(_Decimal32 x, _Decimal32 y);     /* C++ only */
_Decimal64  fmod(_Decimal64 x, _Decimal64 y);     /* C++ only */
_Decimal128 fmod(_Decimal128 x, _Decimal128 y);    /* C++ only */

General description

Calculates the floating-point remainder of x/y. The absolute value of the result is always less than the absolute value of y. The result will have the same sign as x.

Returned value

If successful, the function returns the floating-point remainder of x/y.

If y is 0, the function sets errno to EDOM and returns NaNQ. No other errors will occur.

Example

⁄* CELEBF83

   This example illustrates the fmodd32() function.

*⁄

#define  __STDC_WANT_DEC_FP__
#include <math.h>
#include <stdio.h>

void main(void)
{
   _Decimal32 x, y, z;

   x = -10.0DF;
   y = 3.0DF;
   z = fmodd32(x, y);

   printf("fmodd32( %Hf, %Hf ) = %Hf\n", x, y, z);
}
