currency

I read about NSLocaleCurrencySymbol, but where would I find the variable used to determine the "number of decimal places" used in a country's currency? I.E. In the USA, it's common to see dollar amounts written with 2 decimal places: $1.23 What about many other countries? Jorge Brana There are a number of other countries that display a different number of decimal places. 2 is the majority, 0 (no cents in their currency, e.g., Japan) is the largest minority, 3 is used in just a few. No other number that I know off. When exchange rates are quoted, more decimals are typically used. The currencies

I'm new to Swift programming and I've been creating a simple tip calculator app in Xcode 8.2, I have my calculations set up within my IBAction below. But when I actually run my app and input an amount to calculate (such as 23.45), it comes up with more than 2 decimal places. How do I format it to .currency in this case? @IBAction func calculateButtonTapped(_ sender: Any) { var tipPercentage: Double { if tipAmountSegmentedControl.selectedSegmentIndex == 0 { return 0.05 } else if tipAmountSegmentedControl.selectedSegmentIndex == 1 { return 0.10 } else { return 0.2 } } let billAmount: Double? =

I am trying to get the symbols of the currencies based on their Locale. But instead of returning a symbol, it is returning the code. I have a snippet: import java.util.Currency; import java.util.Locale; public class CurrencyFormat { public void displayCurrencySymbols() { Currency currency = Currency.getInstance(Locale.US); System.out.println("United States: " + currency.getSymbol()); } public static void main(String[] args) { new CurrencyFormat().displayCurrencySymbols(); } } For Locale.US it is giving symbol $ but If I replace Currency currency = Currency.getInstance(Locale.US); with Currency

I'm looking for a way to automate a transfer from one bank account to another, without the end user having to login to something like paypal or amazon payments to complete the process (by transferring their on-line balance to their bank account). I've looked around online a bit, and found some vendors that seem to be able to do that, but API documentation doesn't make me feel sure about it. Can anyone recommend a service they've used to do something like this? Obviously I'm looking for a web based API. The complete process is a middleman site that collects payments (that's the easy part), then

What is a regular expression suitable for C# that'll validate a number if it matches the following? $1,000,000.150 $10000000.199 $10000 1,000,000.150 100000.123 10000 Or the negative equivalents? You can use csmba's regex if you make one slight modification to it. ^\$?(\d{1,3},?(\d{3},?)*\d{3}(.\d{0,3})?|\d{1,3}(.\d{2})?)$ I think ssg is right. It's not a really good use of Regex, especially if your software has to deal with non-US centric data entry. For instance, if the currency symbol is the Euro, or the Japanese Yen or the British Pound any of the other dozen currency symbols out there?

What class should I use for representation of money to avoid most rounding errors? Should I use Decimal , or a simple built-in number ? Is there any existing Money class with support for currency conversion that I could use? Any pitfalls that I should avoid? I assume that you talking about Python. http://code.google.com/p/python-money/ "Primitives for working with money and currencies in Python" - the title is self explanatory :) Never use a floating point number to represent money. Floating numbers do not represent numbers in decimal notation accurately. You would end with a nightmare of
