摘要
在已实现了高精度四则运算及乘方运算的基础上,利用枚举法和牛顿迭代法对高精度开方作了较为深入的研究,分析了两种方法各自的特点,并分别用 C 语言实现了高精度开方运算.
On the basis of realization of high precision four-operation and high pre- cision power,algorithm of extract with high precision is thoroughly studied by uti- lizing enumeration method and Newton iteration method.Their characteristics are analysed respectively and the programs in C language to extract with high precision are realized respectively.
