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.

I want to get the result as a floating point number and then round up to the nearest int.

Something like this:

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

How should I do this?

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);
