Scores Approximation of Irrational Numbers——the Best Rational Number Approximation

本文讨论用分数近似表示无理数的理论和方法,也就是最佳有理数逼近问题。文中给出了若干个常用无理数的最佳逼近分数,所用方法在科学研究和技术数据处理中有广泛用途。

This article discusses with the score expresses the irrational number theory and the method approximately, also is the best rational number approximation problem. In the article has given certain commonly used irrational number optimal approximation score, uses the method has the widespread use in the scientific research and in engineering data processing.
