I.Totally.Agree.

What was wrong with the suggestion of just multiplying by 10 and adding the number?

It's very marginally faster to do the concat way (100,000 reps each comes to .066 seconds for the multiply and add, while it only took .044 for the concat).

But beyond that I dunno.

Source:

Code: Select all

function love.load()
	x = 0
	sx = love.timer.getTime()
	for i=1,100000 do
		x = (x * 10) + 1
	end
	ex = love.timer.getTime()
	y = 0
	sy = love.timer.getTime()
	for i=1,100000 do
		y = tonumber(tostring(y).."1")
	end
	ey = love.timer.getTime()
end
function love.draw()
  love.graphics.print("It took " .. (ex-sx) .. " to multiply x 100,000 times", 5, 5)
  love.graphics.print("It took " .. (ey-sy) .. " to concatenate y 100,000 times", 5, 25)
end
