That's rounded off to an arbitrary number of digits because most calculators can't handle rational numbers.

You mean can't handle irrational numbers? :P

But yeah, ok, that makes sense.

It's a rational number if it can be expressed as a whole-number fraction. These can also be expressed as a repeating decimal (1/3 = 0.333(repeating)) or a terminating decimal (1/4 = 0.25). Some programming languages (primarily the lisp family) have a rational type that's used to avoid rounding errors although the fractions often become unreadable.

Irrational numbers don't have a repeating pattern in decimal notation.

I do know what rational and irrational numbers are.

You said calculators can't handle rational numbers. I was asking if you meant to say they can't handle irrational numbers.
