## 3.257. __nv_remquof

Prototype:

float @__nv_remquof(float %x, float %y, i32* %quo)



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_remquof(x, 0, quo) returns NaN.

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

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