Is their a built-in way of formatting string as $ price, e.g. 12345.45 converted to $12,345.45 ? Assuming you are using Cocoa (or just Foundation), you can use NSNumberFormatter and set its style to currency: NSNumberFormatter *formatter = [[NSNumberFormatter alloc] init]; [formatter setNumberStyle:NSNumberFormatterCurrencyStyle]; ... = [formatter stringFromNumber:number]; By default it uses the locale of your system, but you can change that and lots of other properties, see the NSNumberFormatter API docs. Assuming the price is held in a float, you probably want +localizedStringWithFormat: .

How do I format in Java a number with its leading sign? Negative numbers are correctly displayed with leading - , but obviously positive numbers are not displayed with + . How to do that in Java? My current currency format string is \#\#\#,\#\#\#,\#\#\#,\#\#\#,\#\#0.00 (yes, I need to format positive/negative currency values) Use a negative subpattern, as described in the javadoc for DecimalFormat .

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. As of IAB Version 3 , the SKU details for the purchasable item include a formatted price, which includes

How do you convert a number to a string showing dollars and cents? eg: 123.45 => '$123.45' 123.456 => '$123.46' 123 => '$123.00' .13 => '$0.13' .1 => '$0.10' 0 => '$0.00' Jeremy Ruten PHP also has money_format() . Here's an example: echo money_format('$%i', 3.4); // echos '$3.40' This function actually has tons of options, go to the documentation I linked to to see them. Note: money_format is undefined in Windows. If you just want something simple: '$' . number_format($money, 2); number_format() i tried money_format() but it didn't work for me at all. then i tried the following one. it worked

Right now I have double numba = 5212.6312 String.Format("{0:C}", Convert.ToInt32(numba) ) This will give me $5,213.00 but I don't want the ".00". I know I can just drop the last three characters of the string every time to achieve the effect, but seems like there should be an easier way. First - don't keep currency in a double - use a decimal instead. Every time. Then use "C0" as the format specifier: decimal numba = 5212.6312M; string s = numba.ToString("C0"); This should do the job: String.Format("{0:C0}", Convert.ToInt32(numba)) The number after the C specifies the number of decimal places

I'm looking for a way to convert any amount from one currency to another on a website.

I have once scenario where in i get the currencies as a String, for eg: $199.00 R$ 399,00 £25.00 90,83 € AED 449.00 How do i convert these currencies to double in java? Never use double for representing exact amounts Well, of course you can do, but you need to really understand floating point arithmetic Use a NumberFormat . Whilst it does handle some currencies, it's usually easier just to strip all the currency symbols. The NumberFormat will use Locale to work out the delimiters to use: public static BigDecimal parse(final String amount, final Locale locale) throws ParseException { final
