Every system that uses a fixed finite number of bits to represent numbers

Hi Todd,
This is going to be hard for an intuitive guy like you, but it can be

Hello ToddAndMargo,
The answer to your question depends on how the number is represented.
If you are using a symbolic data type, meaning one that represents a number as a
logical formula akin to program source code, and the operators on that data type
work by manipulating tree expressions

That is not an insult. I am using it as term of admiration.
And I did not dream it up myself. I have had several of
the developers use both magical and Magic Larry powder
on me,
If you wouldn't mind, please stop referring things as being "magical".
There's nothing magical about Raku/Perl6 other than the devs that put in
their time to give you that perception.
They are to be commended for their time and effort.
Also, being condescending as in "he gave up" is uncalled for.

There is no such thing as an irrational number in computing.
Surely there are "close approximations", but that's the best any computer
language can currently do.

This is a complete trivia question.
Is there a test to see if a number is irrational,
such as the square root of two?
And how does Int handle a irrational number? Is
there a limit to magic Larry powder?
