Numeric and Date Format Specifiers

Control how numbers and dates render.

Standard Numeric Formats

Format specifiers are short codes that shape how numbers display. Common ones are N, C, P, F, and D.

using System;

class Program {
    static void Main() {
        double n = 1234.5;
        Console.WriteLine($"{n:N2}");
    }
}

N2 formats a number with thousands separators and two decimal places.

using System;

class Program {
    static void Main() {
        Console.WriteLine($"{1234567.891:N2}");
    }
}
