About Irrational Numbers

An irrational number is a real number that cannot be expressed as a simple fraction of two integers. In decimal form, irrational numbers have non-repeating and non-terminating decimal expansions. Examples include π (pi), √2, and e.

This tool uses a heuristic approach to quickly determine if a number is likely irrational. It checks if the number has a long decimal part, which is a common indicator of irrationality for numbers not explicitly defined as rational (like fractions of small integers).

Note: This tool provides a likely assessment and is not a definitive mathematical proof of irrationality. For rigorous determination, more advanced mathematical methods are required.
