currency

问题 I want to format an amount of money (in Euros) in the user's language in Java, regardless of the country the user is in: final NumberFormat currencyFormat = NumberFormat.getCurrencyInstance(loc); currencyFormat.setCurrency(EUR); currencyFormat.format(new BigDecimal("1.99")); However, the output for different input locales ( loc ) is as follows: nl_NL: € 1,99 nl_BE: 1,99 € nl_DE: EUR 1,99 nl ( new Locale("nl") ): EUR 1,99 So I have two problems The output does depend on country, not just

问题 I'm trying to make a set of classes to deal with localization (mostly the currency part, but also language). I can imagine how the logic could be, but I don't know what names to use for the different languages and currencies. I have seen there are many ISO standards for this, which one should I pick?

问题 I have such examples: USD 10.99 LIR10.99 $ 10.99 $10.99 So the input data may be any 'symbolfloat' or 'symbol float'. I have made something like this: float((str(param[2]).translate(None, '$USDLIR'))) But it can be any world currency, so it must be a universal converter. 回答1: Remove anything from the string which isn't a digit or a decimal point: import re import locale decimal_point_char = locale.localeconv()['decimal_point'] clean = re.sub(r'[^0-9'+decimal_point_char+r']+', '', str(param[2]

问题 All, Our application requires data on ISO countries and currencies (where the data must be up to date). We did purchase country/currency data from ISO themselves, however we still needed to perform alot of manual manipulation of the data, as well as write our own tool to read and process the data into our database. Are we going about getting this data the wrong way? What is the norm in relation to the acquisition of country/currency data? Is there any well known providers out there that are

问题 I am developing an eCommerce application and one of the features is that users can choose their currencies. Now, I noticed that when somebody selects the Russian Ruble, the symbol shows as just a square in Chrome on iOS (version 7.1). Why is that? It should show this: ₽ but it shows this: ▢ Note that I am using the HTML code to display it: ₽ On the desktop version (iMac) it shows fine and I imagine on other operating systems, too. Anybody got a clue why it's not showing in iOS? 回答1: Ruble

问题 Currently learning C++ and this has just occurred to me. I'm just curious about this as I'm about do develop a simple bank program. I'll be using double for calculating dollars/interest rate etc., but there are some tiny differences between computer calculations and human calculations. I imagine that those extra .pennies in the real world can make all the difference! 回答1: In many cases, financial calculations are done using fixed-point arithmetic instead of floating point. For example, the

问题 The infamous question about datatypes when storing money values in an SQL database. However in these trying times, we now have currencies that have worth up to 18 decimal places (thank you ETH). This now reraises the classic argument. IDEAS Option 1 BIGINT Use a big integer to save the real value, then store how many decimal places the currency has (simply dividing A by 10^B in translation)? Option 2 Decimal(60,30) Store the datatype in a large decimal, which inevitibly will cost a large
