还有一个就是找外面写好的高精度库.追问谢谢，有代码提示一下吗，我这里试了一下，依然不行。
追答这个页面有点像大数类那种模式的.看看能不能用得blog.csdn.net/code4101/article/details/23020525
开源中国上有一个比较出名的高精度库www.oschina.net/p/gmp
GNU GMP 详细介绍
Gnu MP 是一个任意精度的数学计算库。
operating on signed integers, rational numbers, and floating point numbers. There is no limit to the precision, except for the ones implied by available memory. It has a rich set of functions, and the functions have a regular interface. It is designed to be as fast as possible, both for small operands and for huge operands. The speed is achieved by using fullwords as the basic arithmetic type, by using fast algorithms with carefully optimized assembly code for the most common inner loops for a lot of CPUs, and by a general emphasis on speed (instead of simplicity or elegance). It is believed to be faster than any other similar library. The advantage increases with the operand sizes for certain operations, since GMP in many cases has asymptotically faster algorithms.
