3.168. __nv_fmod

double @__nv_fmod(double %x, double %y)

Calculate the double-precision floating-point remainder of x / y.

Calculate the double-precision floating-point remainder of x / y. The floating-point remainder of the division operation x / y calculated by this function is exactly the value x - n*y, where n is x / y with its fractional part truncated. The computed value will have the same sign as x, and its magnitude will be less than the magnitude of y.

Note

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

Returns

  • Returns the floating-point remainder of x / y.

  • __nv_fmod( \(\pm 0\) , y) returns \(\pm 0\) if y is not zero.

  • __nv_fmod(x, \(\pm\infty\) ) returns x if x is finite.

  • __nv_fmod(x, y) returns NaN if x is \(\pm \infty\) or y is zero.

  • If either argument is NaN, NaN is returned.
