*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!
