How could I detect if a number is odd?

How could I detect if a number is an even/odd number?

Using the Mod operator or %

What does it do?

The mod operator is basically another way to divide values, but instead of returning the result, it returns the remainder.

Example:

local z = 10 % 2 --This is like 10 / 2 but it will return whats left over
print (z) --This will print 0 because there is no remainder

z = 10 % 3 -- This should not evenly divide
print (z) --This will now print '1', or the remainder

How you could use this

Basically, if you divide a number by two and it has no remainder, it is an even number.

So to check if something is an odd number, you can have it check if the remainder has any value other than 0

if x % 2 == 0 then
	print (x.." is an even number")
else
	print (x.." is an odd number")
end

Try experimenting with this and let me know if it works for you!
