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 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( ± ∞ , y, quo) returns NaN.

  • __nv_remquo(x, ± ∞ , quo) returns x.
