Rounding down on Lua

[Aanson]

Hey guys, quick question...

I've created a button which allows me to increase/decrease the height of ChatFrame by using OnMouseWheel.

The button also shows the height of the ChatFrame with OnSizeChanged:

self.text:SetText("Height: "..ChatFrame1:GetHeight())

It returns though with something like 280.00033324777.

While I appreciate it's accuracy lol, could someone give me a pointer on how I can round down the data that I get from GetHeight()?

Any help would be hugely appreciated .
