Magic Number Calculator

-- I initially used Microsoft Exel to use this, but because of it's limitations I turned it into a nicer and better script.  If you do not know what magic numbers are, don't bother with this script.  If you do, you will find this very useful.

function round(number)
    kek = nil
    local strnum = tostring(number)
    for i=1,#strnum do
        if string.sub(strnum,i,i) == "." then
            kek = tonumber(string.sub(strnum,i+1,i+1))
            kek2 = tonumber(string.sub(strnum,1,i-1))
        end
    end
    if kek ~= nil then
        if kek >= 5 then
            kek2 = kek2 + 1
        else
            kek2 = kek2
        end
    end
    return kek2
end

function removedec(number)
    kek = number
    local strnum = tostring(number)

        if string.sub(strnum,i,i) == "." and string.sub(strnum,i+1,i+1) == "0" and string.sub(strnum,i+2,i+2) == ""  then
            kek = tonumber(string.sub(strnum,1,i-1))
        end
    end
    return kek
end

    kek = false

    end
    return kek
