That works, but put INT in small case. Though typing int (.67) is generally
acceptable C, most people tend to move the brackets around the int.
x = (int) 0.67;

Just be warned: Your example will round down.

Test program:

#include <stdio.h>

int main()
{
    printf(" %d    %d    %d",  (int) 1.1,  (int) 0.9, (int) .67);
}

You would expect them to all round up to 1. Only the first one does.
