偶然又遇到了一道大数题,据说python大数运算好屌,试了一发,果然方便-1 a = int( raw_input() ); //注意这里是按行读入的,即每行只读一个数 b = int( raw_input() ); print a+b; print a*b; print a/b; print a%b;…

收藏的一段关于java大数运算的代码: package study_02.number; import java.math.BigDecimal; import java.math.BigInteger; public class BigNumber { // 默认除法运算精度,即保留小数点多少位 private static final int DEFAULT_DIV_SCALE = 10; // 这个类不能实例化 private BigNumber() { } /** * 提供精确的加法运算…

Description Bulls are so much better at math than the cows. They can multiply huge integers together and get perfectly precise answers ... or so they say. Farmer John wonders if their answers are correct. Help him check the bulls' answers. Read in tw…

用JAVA 实现算术表达式(1234324234324 + 8938459043545)/5 + 343434343432.59845 因为JAVA语言中的long 定义的变量值的最大数受到限制,例如123456789987654321这样的整数就不能存放在long类型的变量中,如果这样两个大数相加或相乘,产生的结果会更大.比如,JAVA语言中如果使用long l = 1000000000这样定义没错,但如果加上2000000000变成 1000000000+2000000000测试结果就为-1…

基础加法大数运算: [https://vjudge.net/problem/HDU-1002] 题目: 输入两个长度不超过1000的整数求出sum. 思路: 由于数字很大不能直接加,用字符串形式输入,分离每个字符(a[i]=sa[i]-'0',b[i]同理),并分别存入两个数组,再选取len=max(alen,blen); 从个位开始进行加,注意进位即可. 代码: /*A+B大数运算*/ #include<bits/stdc++.h> using namespace std; int main…
