目前已有若干版本的子程序库公开发表，它们各有特色。本程序库中的开平方算法为快速逼近算法，它能达到牛顿迭代法同样的精度，而速度加快二十倍左右，超过双字节定点除法的速度-At present, a number of published versions of the subroutine library, they have their own characteristics. The library of the square root algorithm for fast approximat

Gauss-Seidel方法，是Jacobi方法的一种改进，可以认为是一种不动点迭代-Gauss-Seidel method is an improvement of the Jacobi method, that is a fixed point iteration

Jacobi超松弛迭代是不动点迭代的一种，但收敛速度一般来讲并不理想。-Jacobi over relaxation is a fixed point iteration, the convergence rate is not ideal.

本程序库中的开平方算法为快速逼近算法，它能达到牛顿迭代法同样的精度，而速度加快二十倍左右，超过双字节定点除法的速度。-The libraries in the open square algorithm for rapid approximation algorithm, it can achieve the Newton iteration method the same precision, and about twenty times faster, more than double by
