c++ integer division

Question

Say I\'ve got

SDL_Rect rect;
rect.x = 5; // rect.x is of type \"Uint16\"
int y = 11;

and I want to perform the operation rect.x/y

Answer 1

Cast either rect.x or y to float, and then do the division. This will force the entire division operation to take place in floating point.

float result = rect.x/(float)y;
int rounded = ceil(result);

Answer 2

You need to cast your variables.

float result = (float)rect.x / (float)y;
int rounded = ceil(result);

Answer 3

You can do this without any floating point types. If x and y are positive integers, then x divided by y, rounded up is (x+y-1)/y.
