Is there an in-built/well-defined way to do this, or will I pretty much have to roll my own? [Edit]: Here is my first stab... static class ByteFormat extends NumberFormat { @Override public StringBuffer format ( double arg0 , StringBuffer arg1 , FieldPosition arg2 ) { // TODO Auto-generated method stub return null ; } @Override public

Easiest way to convert int to string in C++

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: What is the easiest way to convert from int to equivalent string in C++. I am aware of two methods. Is there any easier way? 1. int a = 10; char *intStr = itoa(a); string str = string(intStr); 2. int a = 10; stringstream ss; ss 回答1: C++11 introduces std::stoi (and variants for each numeric type) and std::to_string , the counterparts of the C atoi and itoa but expressed in term of std::string . #include std::string s = std::to_string(42); is therefore the shortest way I can think of. You can even omit naming the type, using the auto keyword:

Jade - convert new lines to <br/> and keep the content encoded

Is there a way to convert the new lines such as \n to br tags and at the same time keep the other content encoded? For example .replace(/\n/g,'') applied over the encoded value should do the work. However I am not sure how to encode the value and get the result. Is there any helper for this? 回答1: You can use jades escape method and replace the linebreaks in the return value of that like so: p !{escape(foo).replace(/\n/g, ' ')} I am not aware of any built-in functionality for your

My Tactic goes like this: Separate the digits to three and put them on Array ( finlOutPut ), from right to left. Convert each group (each cell in the finlOutPut array) of three digits to a word (this what the triConvert function does). If all the three digits are zero convert them to "dontAddBigSuffix" From Right to left, add thousand, million, billion, etc . If the finlOutPut cell equals "dontAddBigSufix"
