I would assume I could do this with setNegativeFormat: but reading Apple's oh so thorough docs I am left scratching my head: setNegativeFormat: Sets the format the receiver uses to display negative values. - (void)setNegativeFormat:(NSString *)aFormat Parameters aFormat A string that specifies the format for negative

问题 My locale uses a comma , , and not a dot . for decimal separator. In MVC3, when I open an Edit view where the decimal values are shown with @Html.EditorFor(model => model.MyDecimalVal) the value is shown correctly. When I enter value with comma, I get error "Value is not a number" and if I enter value with dot, I get no error, but actually no value is saved. How to handle this situation? 回答1: Getting around with this by tweaking your validation logic has been already explained so here is a

问题 in my code i use integers multiplied by 100 as decimals (0.1 is 10 etc). Can you help me to format output to show it as decimal? 回答1: int x = 100; DecimalFormat df = new DecimalFormat("#.00"); // Set your desired format here. System.out.println(df.format(x/100.0)); 回答2: I would say to use 0.00 as format: int myNumber = 10; DecimalFormat format = new DecimalFormat("0.00"); System.out.println(format.format(myNumber)); It will print like: 10.00 The advantage here is: If you do like: double

问题 Is it possible to use any fraction symbol on a website, represented as ¼ rather than 1/4 for example? From what I've gathered, these are the only ones I can use: ½ ⅓ ⅔ ¼ ¾ Is this right and why is that?

问题 I am wondering if it is possible, using the String.format method in Java, to give an integer preceding zeros? For example: 1 would become 001 2 would become 002 ... 11 would become 011 12 would become 012 ... 526 would remain as 526 ...etc At the moment I have tried the following code: String imageName = "_%3d" + "_%s"; for( int i = 0; i < 1000; i++ ){ System.out.println( String.format( imageName, i, "foo" ) ); } Unfortunately, this precedes the number with 3 empty spaces. Is it possible to
