题目链接:https://cn.vjudge.net/problem/POJ-1001 以前写过一个高精度乘法,但是没有小数点,实现起来也没什么难得, 现在把代码都般过来,等会把旧电脑弄一弄,暂时就不写题解了 代码 #include <cstdio> #include <cstring> struct BigInteger{ int dot, size; char num[600]; BigInteger(int size=0, int dot=0):size(size),dot(…

今天看到这道题了 poj1001 题目地址是http://bailian.openjudge.cn/practice/1001/ 英文看得懂,可是算法不明白,所以转别人的文章,留着给学生看看:乔高建(高精度) 解题思路 这道题属于高精度乘法运算,要求输入一个实数R一个指数N,求实数R的N次方,由于R有5个数位,而N又特别大,因此用C++自带的数据类型放不下.解题思路是通过数组储存每次乘积结果和底数的每一位数,按照乘法上下算式的方法,计算底数乘数数组每一位与临时结果数组的每一位的乘积,(因为算术运…

题目是POJ1001 Exponentiation  虽然是小数的幂 最终还是转化为大整数的乘法 这道题要考虑的边界情况比较多 做这道题的时候,我分析了 网上的两个解题报告,发现都有错误,说明OJ对于错误的判断还不够严厉. 对边界情况的讨论其实应该是思维严密的表现,当然这并不能表明我写的一点错误都没有,只是多多分析一下还是很有好处的. #include <iostream> #include <fstream> #include <string> #include &l…
