C# Convert.ToInt32(double) Method

Convert.ToInt32(double) Method is used to convert a specific double value (a double precision floating point number) to its equivalent integer (int 32 bytes signed number).

Syntax:

    int Convert.ToInt32(double value);

It accepts a double value/variable as an argument and returns its equivalent signed integer.

Example:

    Input: 
    double a = 1023.12;
    Output:
    1023

    Input: 
    double a = 1023.56;
    Output:
    1024

Code:

using System;
using System.Text;

namespace ConsoleApplication3
{
    class Program
    {
        static void Main(string[] args)
        {
            double a = 1023.00;
            double b = 1023.56;
            double c = 1023.12;

            Console.WriteLine("value of a: {0}, type of a: {1}", a, a.GetType());
            Console.WriteLine("value of b: {0}, type of b: {1}", b, b.GetType());
            Console.WriteLine("value of c: {0}, type of c: {1}", c, c.GetType());

            //converting to Int32 & printing values & types
            Console.WriteLine("value: {0}, type: {1}", Convert.ToInt32(a), Convert.ToInt32(a).GetType());
            Console.WriteLine("value: {0}, type: {1}", Convert.ToInt32(b), Convert.ToInt32(b).GetType());
            Console.WriteLine("value: {0}, type: {1}", Convert.ToInt32(c), Convert.ToInt32(c).GetType());

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

Output

value of a: 1023, type of a: System.Double
value of b: 1023.56, type of b: System.Double
value of c: 1023.12, type of c: System.Double
value: 1023, type: System.Int32
value: 1024, type: System.Int32
value: 1023, type: System.Int32
