General description

The fdim functions compute the positive difference between x and y.

Notes:

To use IEEE decimal floating-point, the hardware must have the Decimal Floating-Point Facility installed.
These functions work in IEEE decimal floating-point format. See IEEE binary floating-point for more information

Returned value

The fdim functions return the positive difference between x and y.

Example

⁄* CELEBF76

   This example illustrates the fdimd32() function.

*⁄

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

int main(void)
{
   _Decimal32 x = 56789.70DF, y = 56790.00DF, z;

   z = fdimd32(y, x);

   printf("The result of fdim32(%Hf, %Hf)\n is %Hf\n", y, x, z);
   return 0;
}
