C# Fixed-Point (“F”) Format Specifier

The ("F") format specifier converts a number to a string of the following form −

"-ddd.ddd…"

Above, "d" indicates a digit (0-9).

Let us see an example.

Here, if we will set (“F3”) format specifier to add three values after decimal places, for let’s say, 212.

212.000

The following is another example −

Example

 Live Demo

using System;
using System.Globalization;
class Demo {
   static void Main() {
      int val;
      val = 38788;
      Console.WriteLine(val.ToString("F",CultureInfo.InvariantCulture));
      val = -344;
      Console.WriteLine(val.ToString("F3",CultureInfo.InvariantCulture));
      val = 5656;
      Console.WriteLine(val.ToString("F5",CultureInfo.InvariantCulture));
   }
}

Output

38788.00
-344.000
5656.00000
