The irrationality of pi doesn't come in at all to the
problem of physically measuring things. You can compute pi to a
precision that enormously exceeds the precision with which you can
compare two lengths for equality.

If the number produced by the computation terminates ie does not go on
for an infinite number of decimal places, then it is not pi. However
many decimal places you put in, it is not pi: It is an approximation
to pi.

But this is irrelevant to the physical world, since you cannot compare
things exactly. For it to be significant you have to be working with
some abstraction instead of physical objects, and once you're working
with an abstraction there's no reason to do it in terms of decimal
places or rational fractions.
