解题报告： 思路：和UVA - 674题目解法一样。这题要注意精度。 代码： #include<bits/stdc++.h> using namespace std; typedef long long ll; const ll N = 3e4+10; const ll dic[11] = {5, 10, 20, 50, 100, 200, 500, 1000, 2000, 5000, 10000}; ll dp[N]; double n; void init(){ dp[0] = 1; for(ll i=0; i<11; ++i){ for(ll j=dic[i]; j<N; ++j){ dp[j] += dp[j - dic[i]]; } } } int main(){ init(); while(~scanf("%lf", &n)){ ll nn = n*100+0.5; if(!nn)break; printf("%6.2f%17lld\n", n, dp[nn]); } return 0; } 来源： CSDN 作者： baronLJ 链接： https://blog.csdn.net/jun_____/article/details/104575897

与预定义类型的用户类型强制转换 using System; namespace 实现用户定义的类型强制转换 { class Program { static void Main(string[] args) { //Console.WriteLine("Hello World!"); //隐式转换 //var balance = new Currency(10,50); // float f = balance; //System.Console.WriteLine(balance); // System.Console.WriteLine(f); //显示转换 //下面代码可以成功编译 // float amount = 50.35f; // Currency amount2 = (Currency)amount; // System.Console.WriteLine(amount.ToString()); // Currency c = new Currency(50,35); // float f = c; // c = (Currency)f; // System.Console.WriteLine(c); } } public struct Currency{ public uint Dollars{get;} public ushort Cents{get;}

可以将文章内容翻译成中文,广告屏蔽插件可能会导致该功能失效(如失效，请关闭广告屏蔽插件后再试): 问题: I'm in a bit of a weird situation, I am dealing with currency in my we app. On the model side, I am saving currency as cents before sending to the server as I don't want to deal with decimal points on the server side. In the view however, I want the to display normal currency and not cents. So, I have this input field where I take the data from dollars and change it to cents: And when there's a change in the input value, I change it back to cents before sending it upstream: handleUpdate: function(e) { var value = e.target.value; // changing
