currency

问题 I have an Android app using In-App-Purchase that caters to an international audience, so I expect payments in different currencies. Of course I would like to show the items for purchase with the user's local currency, but I don't really know how. Using the region or language of a user seems like a bad indicator, as the currency seems to depend on the region of the Market account the user is using and not on the device settings. How can I find out which currency a user will pay in? Thanks. 回答1

问题 In my view I have the following call. <%= Html.EditorFor(x => x.Cost) %> I have a ViewModel with the following code to define Cost. public decimal Cost { get; set; } However this displays a decimal value with four digits after the decimal (e.g. 0.0000). I am aware of Decimal.toString("G") (MSDN) which appears to solve this issue, but I'm uncertain of where to apply it. One solution seems to be create a partial view "Currency.aspx". <%@ Control Language="C#" Inherits="System.Web.Mvc

问题 How do I get NumberFormat.getCurrencyInstance() to print negative USD currency values with a minus sign? 回答1: It requires a little tweaking of the DecimalFormat returned by NumberFormat.getCurrencyInstance() to do it in a locale-independent manner. Here's what I did (tested on Android): DecimalFormat formatter = (DecimalFormat)NumberFormat.getCurrencyInstance(); String symbol = formatter.getCurrency().getSymbol(); formatter.setNegativePrefix(symbol+"-"); // or "-"+symbol if that's what you

问题 What is the proper way to format currency if you are formatting a currency that is not the native currency of the current culture? For example, if I am formatting US Dollars for a fr-FR culture do I format it like a en-US culture ( $1,000.00 ) or as an fr-FR culture but changing the Euro symbol to a US Dollar symbol ( 1 000,00 $ ). Perhaps something else ( $1 000,00 or 1 000,00 USD )? 回答1: There's no absolute rules here but a couple of guiding principles: Try and use the number format for

问题 I want to find out the currency locale on user's iphone programmatically. That means, if user is in US Store, the currency locale should be USD, for Australia, it should be AUD. My purpose of this task is to try to convert the item price listed on our app to be nearly match with the price that AppStore ask. For example, if we sell a video 3 usd, and an Australian wants to buy it, then I should show 2.8 AUD in my app screen. It will reduce the calculation in the user over the real price in his
