Thread: Using the sleep function with a float

I have written this code and it will work with an interger but not a float. I have tried casting but it does not run correctly. I want to pause for 0.5 seconds when each line prints. Here is the code:

Code:

#include <stdio.h>
#include <time.h>

int main() {

    int n = 1;
    char fz[] = "Fizz";
    char bz[] = "Buzz";
    char fb[] = "FizzBuzz";
    float sec = 0.5;

    for ( n = 1; n < 101 ; ++n ) 
        if ( n % 15 == 0 ) {
            printf("%s\n", fb);
            sleep((int)sec);
        } else if ( n % 5 == 0 ) {
            printf("%s\n", bz);
            sleep((int)sec);
        } else if ( n % 3 == 0 ) {
            printf("%s\n", fz);
            sleep((int)sec);
        } else {
            printf("%d\n", n);
            sleep((int)sec);
        }

    return 0;

}

If I change the function line to sleep(1); it works but is a bit slow.
