that's real calculation
I don't get it, who on earth said you have to convert everything to decimals to be the "REAL calculation"

I don't wanna argue about what is the real calculation or not.
In this case Pi is more like operation. We already have represented operations. For example divide is same as Pi

both of them are just different representations of the same objective existence of some certain information, like, simply the distance of some constant dot (dot "Pi") and dot "0" on the axis
it's just this piece of information will need infinite characters if you wanna represent it within the decimal system, BUT, it can be represented with finite characters by other systems, like "Pi"
like, 0.3333... (1/3) is an infinite decimal under the decimal system, but, it's just "1", a single character under the trinary system
if you're still confused, think about 15(dec) and 0xF
