<p>To determine if a number is rational or irrational, the calculator checks if the number can be expressed as a fraction of two integers. If it can, the number is rational. If not, it is irrational. Common examples of irrational numbers include<a>square</a>roots of non-<a>perfect squares</a>and numbers like π and e.</p>
