Please add to the description whether conversion to int rounds or truncates any fractional values. Thank you.
Conversion to int follows standard C rules - fractional parts are truncated.
And it hurts nothing to say so on that page. And puts that piece of information, for new C programmers (or those like me, who haven't written C since 1998, and can't find their K&R) right where they'll find it easily if they're here looking for how to program their Arduino.
