I'm not sure how I want to say this but..

Is there a way to make a If statement that will run one command when a variable is a odd and another command when the variable is a even

lets say ..


y=5
thenumber=tonumber(y)

if thenumber="odd" then

print("durp")

else if thenumber="even" then

print("not durp")
end

Plz pay no atention to spelling and the failure code up there..

I just want to know what I would use instead of "odd" and "even"

PS My english might be suckish…
Also.. how to I set something to be a spoiler.. i dont want anyone to read through the code if they already know what i mean..

hope there is something like this :o/>/>

Oh wait would i use this as

y=read() –your number
thenumber=bit.band(y,1)

if thenumber== ("1") then
print ("odd")

else if thenumber==("0") then
print("even")

end

You can use


print("Even or odd?")
i = tonumber(read())
if i%2 == 1 then
print("Odd.")
else
print("Even.")
end

No, if i is an odd number, it returns 1, if it is even it returns 0. It's a remainder operator.
