Question

I am following a tutorial on how to make a game with SDL. At a certain point in the tutorial I need to calculate the game’s FPS. The tutorial does the following:

caption << "Average Frames Per Second: " << frame / ( fps.get_ticks() / 1000.f );

Now, I know exactly what the code does, except for the part where it divides by 1000.f. I’ve been looking but just can’t find what .f means.

So my question is, what does .f mean? And why is it there?

Answer 1

1000 is an int literal.

1000. is a double literal.

1000.f is a float literal.
