number-formatting

I have been storing phone numbers as longs and I would like to simply add hyphens when printing the phone number as a string. I tried using DecimalFormat but that doesn't like the hyphen. Probably because it is meant for formatting decimal numbers and not longs. long phoneFmt = 123456789L; DecimalFormat phoneFmt = new DecimalFormat("###-###-####"); System.out.println(phoneFmt.format(phoneNum)); //doesn't work as I had hoped Ideally, I would like to have parenthesis on the area code too. new DecimalFormat("(###)-###-####"); What is the correct way to do this? You can use String.replaceFirst

I want to write a method that will take an integer and return a std::string of that integer formatted with commas. Example declaration: std::string FormatWithCommas(long value); Example usage: std::string result = FormatWithCommas(7800); std::string result2 = FormatWithCommas(5100100); std::string result3 = FormatWithCommas(201234567890); // result = "7,800" // result2 = "5,100,100" // result3 = "201,234,567,890" What is the C++ way of formatting a number as a string with commas?

How do I format 1000000 to 1.000.000 in Python? where the '.' is the decimal-mark thousands separator. If you want to add a thousands separator, you can write: >>> '{0:,}'.format(1000000) '1,000,000' But it only works in Python 2.7 and higher. See format string syntax . In older versions, you can use locale.format() : >>> import locale >>> locale.setlocale(locale.LC_ALL, '') 'en_AU.utf8' >>> locale.format('%d', 1000000, 1) '1,000,000' the added benefit of using locale.format() is that it will use your locale's thousands separator, e.g. >>> import locale >>> locale.setlocale(locale.LC_ALL, 'de

I am trying to parse a string like "$45.59" into a decimal. For some reason I am getting exception that the input was not in the correct format. I don't care about all the localization stuff because this is not going to be a global program. Here is what I am doing. Do you see any problems? NumberFormatInfo MyNFI = new NumberFormatInfo(); MyNFI.NegativeSign = "-"; MyNFI.NumberDecimalSeparator = "."; MyNFI.NumberGroupSeparator = ","; MyNFI.CurrencySymbol = "$"; decimal d = decimal.Parse("$45.00", MyNFI); // throws exception here... How about using: decimal d = decimal.Parse("$45.00",
