Rounding numbers up or down.[resolved]

[Jackolas]

I have a question (probably really simple to fix)

atm I'm working on a script and in the configure I have for example how much exp an actor needs to lose.
now in a script I have this part:

Spoiler: ShowHide

  def remove_exp
    if Jackolas_GameOver::LoseExp
      if Jackolas_GameOver::ExpAmount >=1
        for actor in $game_party.actors
          explose = Jackolas_GameOver::ExpAmount
        end
      else
        for actor in $game_party.actors
          explose = actor.exp * Jackolas_GameOver::ExpAmount
        end
      end
      for actor in $game_party.actors
        actor.exp -= explose
      end
    end
  end

if I fill in like 0.5 in the config it works like a dream. no errors and 50% is removed.
only problem is that he puts now 1 number behind the "." in the number, like 10.0 exp  (if you know what I mean)
my question is how can I round that up/down so its a whole number again?
or prevent it from happening.

(yes I know I still need to build in a safety check so it won't try to remove exp below 0)

Use .round or .to_i to turn it into an integer. I suggest .to_i even tough it just truncates the numbers behind the decimal separator. You can apply that at the very end "actor.exp = actor.exp.to_i"

works like a charm
