Format decimal number

Question

I have decimal number always in US format, that is with decimal point. But some countries have comma instead of decimal point.

This will format string in current culture:

   string.Format("{0:F2} {1}", 100.0018, '€')

Result is: 100,00 and it has comma instead of point as wanted.

Is there some function to format on so many decimal points as it is input value, in my case 100,0018?

I have tried with this:

Decimal.TryParse("100.0018", System.Globalization.NumberStyles.Any, System.Globalization.CultureInfo.CurrentCulture, out value);

but the result is 10000 instead of 100,0018

Answer 1

You, probably, want something like this:

 string.Format("{0:0.00###############} {1}", 100.0018, '€')

in order to have at least two digits after the decimal point:

100      -> 100.00 €      
100.0018 -> 100.0018 €  

Answer 2

这应该可以解决问题：

string.Format("{0:#,#.#####}", 100.0018)

Answer 3

You can use NumberFormat :

class Program
{
    static void Main(string[] args)
    {
        var brazil = new CultureInfo("pt-BR");
        var usa = new CultureInfo("en-US");

        Console.WriteLine(100.0018m.ToString(brazil.NumberFormat));
        Console.WriteLine(100.0018m.ToString(usa.NumberFormat));

        Console.ReadKey();
    }
}

Answer 4

My solution vould be: string.Format(new CultureInfo("en-US"), "{0:F2} {1}", 100.0018m, '€'); Result: 100.00 €

Answer 5

string.Format("{0:0.00###############} {1}", 100.0018, '€');

您还可以使用CultureInfo.CreateSpecificCulture获取货币

Answer 6

如果字符串，则可以使用replace，否则可以使用format

s = "100.0018".Replace(".", ",")
