Lua script to convert numbers from base 10 to base 2

toBinary-snip.lua

-- By xDeltaXen from https://devforum.roblox.com/t/binary-conversion-in-lua/1718171

-- This function takes in a number and returns its binary form as a string
function toBinary(num)
	local bin = ""  -- Create an empty string to store the binary form
	local rem  -- Declare a variable to store the remainder

	-- This loop iterates over the number, dividing it by 2 and storing the remainder each time
	-- It stops when the number has been divided down to 0
	while num > 0 do
		rem = num % 2  -- Get the remainder of the division
		bin = rem .. bin  -- Add the remainder to the string (in front, since we're iterating backwards)
		num = math.floor(num / 2)  -- Divide the number by 2
	end

	return bin  -- Return the string
end

-- Example usage
