Question:
Do irrational numbers like pi have exact locations on a
number line?

Replies:
Yes. Irrationals have exact values, hence they have exact positions on the
number line. You just can't write down the exact value in decimal (or any
other RATIONAL base) notation because it's a non-repeating decimal
fraction.

An interesting note is that the transcendentals (irrationals
like pi) far outnumber the "ordinary irrationals" and rationals combined.
