All reasonable men will try to learn the language before programming.
The mentioned behavior is the one C is supposed to have, whether you
like it or not. It one of the first thing I teach in my C classes:
type promotions in expression. They may be dumb, or may not, I will
not argue on that. But being reasonable is knowing the tool before
trying to use it.

Is this also a bug?

int i =3D 1;
int j =3D 2;
double result =3D i / j;
printf("%lf\n", result);

results in 0 being output. Oh my god, C can't perform arithmetic
division! More fun with C?
