Why does this integer division yield 0?

Question

Could someone tell me why the following code is outputting 0 at the marked line?

It seems as if everything is correct but then when I try to get the re

Answer 1

When you divide 2 numbers in C and the denominator is integer, the compiler intends it as an integer division. Therefore, if you divide 1 divided 2, it returns zero and not 0.5

Moreover, your output variable is an integer too, hence, if you expect decimal outputs, you won't get it.

You can fix it by doing:

float timeLapseInterval = totalLengthSecs / (float)totalFrames;

printf("\n\n%f", timeLapseInterval);

I hope this helps
