Abstract.The purpose of the present paper is to introduce an alternative method for computing approximants of a continued fraction. Although the method is based upon established theory for tails of continued fractions - right tails and wrong tails - it has never been presented in this form. The main idea is to illustrate how wrong tails can be used in the computation. This is a consequence of the stability of the algorithm for wrong tails.
