## 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; 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; 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
