*Not necessarily. If you draw a diagonal on a square on a computer screen, it will be made up of a discrete number of pixels despite what Pythagoras' theorem calculates. Irrational in the real world may just be an illusion.* I was trying to mark a distance in real world which is irrational according to a rational unit(Width of pixels), and for such diagonal the distance is an irrational number, although it might be made up of rational numbers of another irrational unit (diagonal pixels) I mean there's some irrational distance out there!
