_Decimal128 remainderd128 (x, y)
_Decimal128 x;
_Decimal128 y;The remainder, remainderf, remainderl, remainderd32, remainderd64, and remainderd128 subroutines return the floating-point remainder r=x - ny when y is nonzero. The value n is the integral value nearest the exact value x/y. When | n x/y |=½ , the value n is chosen to be even.
| Item | Description |
|---|---|
| x | Specifies the value of the numerator. |
| y | Specifies the value of the denominator. |
Upon successful completion, the remainder, remainderf, remainderl, remainderd32, remainderd64, and remainderd128 subroutines return the floating-point remainder r=x - ny when y is nonzero.
If x or y is NaN, a NaN is returned.
If x is infinite or y is 0 and the other is non-NaN, a domain error occurs, and a NaN is returned.
