float time = 1652 / 100.0;
int hours = (int)time;
int minutes = (time - hours) * 100;
hours is 16, minutes is 52.
Also, you are doing time calculation and storage wrong. What you really want is a variable that accumulates time in the smallest unit that you want to store and then calculate the time of day from there.
Also, Dico, I like your way of opening doors with tanks. All kidding aside, how are you going to take care of things like kerning with that?
