3.277. __nv_remquo

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

Compute double-precision floating-point remainder and part of quotient.

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.

Note

For accuracy information, see the CUDA C++ Programming Guide, Mathematical Functions Appendix, Double-Precision Floating-Point Functions section.

Returns

Returns the remainder.

• __nv_remquo(x, 0, quo) returns NaN.

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

• __nv_remquo(x, \(\pm \infty\) , quo) returns x.
