Item Sell Price

[mjshi 2]

Okay, so in Scene_Shop I found this:

  #--------------------------------------------------------------------------
  # * Get Sale Price
  #--------------------------------------------------------------------------
  def selling_price
    @item.price / 2
  end
end

And realizing that I wanted to make selling back items worth more than half price, I proceeded to change it to this:

  #--------------------------------------------------------------------------
  # * Get Sale Price
  #--------------------------------------------------------------------------
  def selling_price
    @item.price * 0.75
  end
end

But what ended up happening was that upon selling back a "potion" worth 50 G, it returned a float number of 37.5 G

Is there any way to "round" a float number in Ruby code?

 

EDIT: no need to trouble about rounding "up" or "down", just always round up xD

 

EDIT 2: I found that even when multiplying "50" by 0.8, which would give a whole number, still returns a float with a ".0" at the end. So.. float to int conversion, anyone? .-.

If you want the item to be sold at 75% write it like this instead:

 

(@item.price / 4) * 3

Or just add .to_i at the end. Like,

(@item.price * 0.75).to_i

Strange that when I use R_Valkyrie's suggestion, an item at 50 G comes out to 36 (50/4 = 12.5, probably rounded to 12, then multiplied by 3) whereas Glasses's suggestion makes it come out as a 37. Anyway, Thanks to both of you!

Or there's this script that does everything:

@ Soulpour777: That's not quite what I was looking for, and I've already found the answer to my question. Thank you for responding though! This thread can be closed now.
