How to cap and round number in ruby

Question

I would like to "cap" a number in Ruby (on Rails).

For instance, I have, as a result of a function, a float but I need an int.

I have very specific instructions, here are some examples:

If I get 1.5 I want 2 but if I get 2.0 I want 2 (and not 3)

Doing number.round(0) + 1 won't work.

I could write a function to do this but I am sure one already exists.

If, nevertheless, it does not exist, where should I create my cap function?

Answer 1

Try ceil:

 1.5.ceil => 2
 2.0.ceil => 2
