Is Infinity a rational number?

Infinity is neither rational nor irrational. Rather, it’s an abstract concept that we use in math. It doesn’t have a numerical value; it just represents something that is larger than any number. So while we can represent a rational number (like 100) or an irrational number like pi, we cannot do the same for infinity.

How do you tell if a number is rational or irrational?
