If the position is 0, it does not print 0, yet still works in a if statement

I’m writing a program to move an instance to another point of the map. How it works is that it will get all the children from a folder and put it in a for i, v, in pairs(). Find the child that’s assigned to the player and matches the X, Y, and Z values. So the script works, the XYZ values match the child’s XYZ values. When I check to see this work with a print, I printed the tiles XYZ values. The X and Z had nothing wrong, but the Y that’s set to 0 did not print 0. Instead it printed 2.4318695068359e-05 and not 0. I think what the problem here is an architecture problem because I’ve come across this problem when I program in Java. The script below.

local player = game.Players.LocalPlayer
local Settlers = game.Workspace.Units.NonDangerous.Settler:GetChildren()
local Tiles = game.Workspace.Tiles:GetChildren()
script.Parent.Activated:Connect(function()
	for i, Settler in pairs(Settlers) do
		if Settler.PlayerName.Value == player.Name then
			for i, tile in pairs(Tiles)do
				if tile.XYZ.Value == Settler.XYZ.Value then
					print("Works")
					print(tile.Name)
					print(StartTile.XYZ.Value)
					print(StartTile.Position.Y)
				end
			end
		end
	end
end)

This is known as floating point imprecision. the NumberValue is likely correcting the floating point inaccuracy during your tile.XYZ.Value == Settler.XYZ.Value comparison, however when printing the StartTile.Position.Y value, you run into the true float.

Try rounding your numbers to a few decimal places to avoid this where necessary.
