A non-terminating decimal expansion is a decimal representation of a number that goes on forever without repeating. For example, the decimal expansion of pi (π) is a non-terminating decimal expansion: 3.14159265359...
When a number has a non-terminating decimal expansion, it means that there is no exact representable decimal result for the number. This is because decimal notation only has a finite number of digits, but the number being represented may have an infinite number of digits after the decimal point.
In some cases, we can approximate the non-terminating decimal expansion of a number by rounding off after a certain number of digits. However, this approximation will never be exact, and there will always be some error in our representation of the number.
