float keyword in C#

C# float keyword: Here, we will find out about the float keyword in C#, what is float keyword, how to utilize it in C#?

C# float keyword:

In C#, the float is a keyword which is utilized to pronounce a variable that can store a floating-point an incentive between the scope of ±1.5 x 10⁻⁴⁵ to ±3.4 x 10³⁸. float keyword is an assumed name of System.Single.

It possesses 4 bytes (32 bits) space in the memory.

Note: To speak to float esteem, we utilize a postfix for F with the worth.

Syntax:

    float variable_name = value;

C# code to show example of float keyword:

Here, we are announcing a float variable num, instating it with the worth 12345.6789f and printing its worth, type and size of a float type variable.

using System;
using System.Text;

namespace Test
{
    class Program
    {
        static void Main(string[] args)
        {
            //variable declaration
            float num = 12345.6789f;

            //printing value
            Console.WriteLine("num: " + num);
            //printing type of variable
            Console.WriteLine("Type of num: " + num.GetType());
            //printing size
            Console.WriteLine("Size of a float variable: " + sizeof(float));
            //printing minimum & maximum value of float
            Console.WriteLine("Min value of float: " + float.MinValue);
            Console.WriteLine("Max value of float: " + float.MaxValue);

            //hit ENTER to exit
            Console.ReadLine();
        }
    }
}

Output:

num: 12345.68
Type of num: System.Single
Size of a float variable: 4
Min value of float: -3.402823E+38
Max value of float: 3.402823E+38
