Converter a Number from Binary to Decimal
In the following example, we will convert a Binary number (1000001) to a Decimal number (65).
Tips: It is recommended to use our online Binary to Decimal converter for better understanding.
Example
C# Compiler
using System;
namespace myApp
{
class Program
{
static void Main(string[] args)
{
int num = 1000001;
int[] arr = new int[50];
int i = -1, j;
int total = 0;
while(num != 0)
{
i++;
arr[i] = num % 10;
num = num / 10;
}
for(j=i; j>=0; j--)
total += (arr[j] * ((int) Math.Pow(2, j)));
Console.Write("Decimal number of 1000001 (binary) is {0}", total);
}
}
}
Output
Decimal number of 1000001 (binary) is 65
Converter any Given Binary Number to Decimal Number
In the following example, we will convert any given binary number to a decimal number.
Example
C# Compiler
using System;
namespace myApp
{
class Program
{
static void Main(string[] args)
{
int num, copyNum;
int[] arr = new int[50];
int i = -1, j;
int total = 0;
Console.Write("Enter a Binary number: ");
num = Convert.ToInt32(Console.ReadLine());
copyNum = num;
while(copyNum != 0)
{
i++;
arr[i] = copyNum % 10;
copyNum = copyNum / 10;
}
for(j=i; j>=0; j--)
total += (arr[j] * ((int) Math.Pow(2, j)));
Console.Write("Decimal number of {0} (binary) is {1}", num, total);
}
}
}
Output
Enter a Binary number: 10
Decimal number of 10 (binary) is 2
