Function to format numbers

[nsanee]

This function will format numbers so you can display large ones in a more user-friendly manner. I wrote it to display big bank account balances more neatly.
Usage

formatNum(12345, ",")
> returns 12,345
formatNum(12345)
> returns 12 345

The function works fine with both strings and integers. If you don't specify the separator string it will use 'space' by default.

function formatNum(str, sep)
    str = tostring(str):reverse()
    str = str:gsub("(%d)(%d)(%d)", '%1%2%3' .. (sep or " "), math.ceil(str:len() / 3)-1)

    return str:reverse()
end

Hope someone finds it usefull
