Definition of Irrational Number
An irrational number is a number that cannot be written as a terminating or repeating decimal.
In other words, an irrational number is a number that can't be written as \(\dfrac{a}{b}\) for some integers, \(a\) and \(b\).
For example, \(\pi\) is an irrational number. Its digits are \(3.141592\dots\). They go on forever, but don't form any pattern that repeats.
Some other examples of irrational numbers are \(\sqrt{2}\) and Euler's number, \(e = 2.71828\dots\).
