In Lua, how can I tell if a number divides evenly into another number? i.e with no remainder? I’m just looking for a boolean true or false.
12/6 = 2 (true)
18/6 = 3 (true)
20/6 = 3.(3) (false)
Compare the remainder of the division to zero, like this:
The modulus operator (
%) returns the remainder of division. For 12 and 6 it is 0, but for 20 and 6 it is 2.The formula it uses is:
a % b == a - math.floor(a/b)*b
