## 3.256. __nv_remquo

Prototype:

```double @__nv_remquo(double %x, double %y, i32* %c)

```

Description:

Compute a double-precision floating-point remainder in the same way as the remainder() function. Argument quo returns part of quotient upon division of x by y. Value quo has the same sign as $\frac{x}{y}$ and may not be the exact quotient but agrees with the exact quotient in the low order 3 bits.

Returns:

Returns the remainder.
• __nv_remquo(x, 0, quo) returns NaN.

• __nv_remquo( $±\infty$ , y, quo) returns NaN.

• __nv_remquo(x, $±\infty$ , quo) returns x.

Note:

For accuracy information for this function see the CUDA C Programming Guide, Appendix D.1, Table 7.
