[小工程]大数类

Posted 2021-01-12 qdscwyy

突然发现自己从来没有写过正儿八经的大数.于是在退役之前写一把.
希望能在用到大数时替代掉慢死的Python.
项目地址Github.com/Frankaiyou/LargeIntegar

Completed

• [x] Input;
• [x] Output;
• [x] Compare size;
• [x] Integar Addition;
• [x] Integar substruction;

ToDoList

• [ ] Fix the memory assignation when addition or substruction;
• [ ] Fix the Output that appear Prefix zero;
• [ ] Fix the Compare;
• [ ] Multiplicaion;
• [ ] division;
• [ ] Manage the memory;

实现思路是用一段连续的int32来表示整段数字, 每个int32只用4位, 为的是方便乘法操作.
