Question

I was looking around and could not find exactly what I was looking for.

I want to round all my numbers up to the whole number.

Example:

5.9 would be 6

5.5 would be 6

5.1 would be 6

5.000001122 would be 6

5.0 would be 5

I was thinking if I put them into ints that would get rid of the decimal but it did not look right as the decimals were just dropping off. Am I correct here?

So I thought about just doing that then adding 1 to the final result which would fix about 99% of the problem but if my result is 5 I do not want to add 1 to it.

How would I go about fixing this issue I have?

Answer 1

You’re looking for the ceil() function from <math.h> or std::ceil() from <cmath>.
