Hi Paul,
Well, it is not unthinkable that a
https://en.wikipedia.org/wiki/Computer_algebra_system (CAS)-like system will be
able to tell that the abstract number sqrt(2) is irrational, as well as some
derivative numbers such as 3 + sqrt(2). E.g:

However, my question to you is: when would you come across an irrational

Every system that uses a fixed finite number of bits to represent numbers
has to represent them as implicit rationals...that is
unless it goes through the trouble of having a finite list of irrational
constants that it represented specially.
sqrt is not equivalent to the mathematical
Hi Todd,
This is going to be hard for an intuitive guy like you, but it can be
proven that 100% of all numbers are irrational (see
https://math.stackexchange.com/questions/1556670/100-of-the-real-numbers-between-0-and-1-are-irrational
).
Except the ones that a computer can do operations on,
