number-formatting

问题 I'm working on an international project and have observed that, in Java, the choice of the decimal separator is based on the Locale's language, not its country. For example: DecimalFormat currencyFormatter = (DecimalFormat) NumberFormat.getInstance(new Locale("it","IT")); System.out.println(currencyFormatter.format(-123456.78)); currencyFormatter = (DecimalFormat) NumberFormat.getInstance(new Locale("en","IT")); System.out.println(currencyFormatter.format(-123456.78)); produces the following

问题 I developed a C# utility class called ExcelGenerator that generate a List of objects to excel. I want to display double numbers in this format : 3 288,523.

问题 I want to convert Price format to number only with a php function Example 1 3,850,000,000 to 3850000000 Example 2 3.850.000.000 to 3850000000 Example 3 3-850-000-000 to 3850000000 回答1: Why not to use regular expressions? This should do the trick: $numbers = preg_replace('/[^0-9]/', '', $price); It's basically telling to match any non-numeric ( ^ stays for different from ) char and then to replace it with nothing. 回答2: You can also use preg_replace('/\D/', '', $number); \D matches all non

问题 I want to turn a "dirty" figure into a properly written currency price. The input figure will be something like 23.99000 and I want to display 23,99 + the Euro symbol. I use this: $price = number_format($price, 2, ',', '')." €"; But the result will be 23,00 € instead of 23,99 €. What am I getting wrong? Thanks! 回答1: Try something like this: <?php $price = 23.99000; $price = sprintf("%01,2f", $price).' €'; echo $price; Output: 23,99 € the f means it'll treat the string as a float, and format

问题 If a number (float) is input such as 12500, the number is converted to money format as 12,500.00. The format will be '###,###,###.##'. How to do this using java and without any apache utils or similar libraries. A comma will repeat after each 3 digits, and the decimal number will be rounded and shown as 2 digits after decimal places. If .5 it should be .50 and if .569 it should be .57. Is there any solution to this problem through regular expression or anything? 回答1: I found following code by

问题 It looks like OData sends Edm.Decimal as "String" also containing the decimal separator. Question: What should be send by OData? Always the same values (for example separator with ".")? Question: How can this data be bound to SAPUI5 control with an automatic locale handling? I am already using new sap.ui.model.resource.ResourceModel({ But numbers are always shown with a dot as separator. 回答1: I think there is a bug in sap.ui.model.type.Float implementation. You can use that data type to

问题 The goal is to use an f-string to round a float to a different number of decimal places based on the size of the number. Is there in-line f-string formatting that works like the following function? def number_format(x: float): if abs(x) < 10: return f"{x:,.2f}" # thousands seperator for consistency if abs(x) < 100: return f"{x:,.1f}" return f"{x:,.0f}" # this is the only one that actually needs the thousands seperator 回答1: Although it is not something that can go in-line in an f-string, the

问题 Since someone marked my other question (NumberFormat parse not strict enough) as duplicate by mistake and did not remove the duplicate label although I pointed out that it was different, I will post the question again together with my solution. Maybe it is helpful to someone. Here we go: I have a JFormattedTextField with a NumberFormat with Locale.US. So the decimal separator is the point and the grouping separator is the comma. Now I type the string "1,23" in this text field and move the
