Check number value

[president vankk]

Hi my dear friends,

How I can check if the number is multiple of 3 and integer on lua? The part of multiple I did check below, but I'm facing some problems with the integer part.

if tonumber(msg) and npcHandler.topic[cid] == 1 then
    local n = tonumber(msg)      
    if (n % 3 == 1) then
        npcHandler:say("This number is not multiple of three.", cid)
        npcHandler.topic[cid] = 0
        return true
    end
end

Thanks.

n % 3 == 0

In computing, the modulo operation finds the remainder after division of one number by another 
(sometimes called modulus). Given two positive numbers, a (the dividend) and n (the divisor), a
 modulo n (abbreviated as a mod n) is the remainder of the Euclidean division of a by n.

If I say 5 to the NPC then will returns it: Are you sure that you want exchange 5 silver medals for 1.6666666666667 golden medal?

Your question was, "multiple of 3 and integer on lua" and i resolved the issue, you did not like my post, so no more help for you.

ooh =(
multiple of 3 and integer, and it is not returning was integer number

That is because you don't understand the n % 3 == 0 formula.
if n % 3 == 0 then
Any number which you divide by 3 with a remainder of 0 is divisible by 3.

Oh sorry, it was by bad, I says using / 3 on the message sended by the NPC. It works perfectly! Thanks.
