GCF/GCD and Irrational Numbers

Questions
1

Hi There,

I’m unsure if this is a bug or not but it seems the GCF() function in desmos is unable to handle irrational numbers. I came across it when working with this situation of: gcf(e,3)=3 which is incorrect.

In a quick pass through it seems to be rounding irrational numbers/decimals to the nearest integer instead of using the decimal.

Is this a known issue or accepted convention that I was just unaware of?

The Greatest Common Factor between irrational numbers is not really well defined …
you can perhaps define it between fractions but between irrational numbers it doesn’t have a true menaning. What should the GCF between pi and e be?
So Desmos does what it can … it just rounds the numbers to nearest integer.
