How to round floating point numbers to the nearest integer in C?

Question

Is there any way to round numbers in C?

I do not want to use ceil and floor. Is there any other alternative?

I came across this code snippet when I Googled f

the googled code works correctly. The idea behind it is that you round down when the decimal is less than .5 and round up otherwise. (int) casts the float into a int type which just drops the decimal. If you add .5 to a positive num, you get drop to the next int. If you subtract .5 from a negative it does the same thing.
