Double X = 10, y = 0; y = x % 2; is this expression correct?

The remainder function and % operator.

The following code cannot be compiled (GCC)

# Include <stdio. h> # include <fenv. h> int main () {Double X = 10; printf ("X % 2 = % lf \ n", X % 2.0); Return 0 ;}

Operator % can only operate on Integer Data (guess, % is implemented based on data bit shift ).

Here, the remainder of the floating point number is called fmod (Doube X, Double Y) in <math. h>.

Double X = 10, y = 0; y = x % 2; is this expression correct?
