How many data types in C# (Floating point types)

Floating point types
C# supports 2 floating point types viz. float and double.

Type # Floating type Data Type Default Value Range

1 float  32-bit single-precision IEEE 754 format 0.0f  1.5 * 10-45 to 3.4 * 1038
2 double  64-bit double-precision IEEE 754 format  0.0d 5.0 * 10-324 to 1.7 * 10308
Table – Floating point types

// Example for floating point types

using System;

    class float_types
    {
        public static void Main(string[] args)
        {
            float f = 12345.12545f;
            double d = 123456789.123456789d;

            Console.WriteLine("Float value: " + f);
            Console.WriteLine("Double value: " + d);
     
        }
    }


 Output:

   Float value:12345.13
 
   Double value: 123456789.123457
