I am using below snippet code and linux 'time' command to calculate the time. void sin_func(void) { double incr = 0.732; double result, count = 0.0;

    printf("%s\n", __func__);

    while (count < 105414350.0) {
            result = sin(count);
            count += incr;
    }

}

Thanks.

Also keep in mind that evaluating this snippet you are also evaluating not printf calls, which not only uses another glibc functions but also issues syscalls.
