Write a program to convert binary to decimal number

Description:

Write a program to convert binary format to decimal number using numeric operations. Below example shows how to convert binary to decimal format using numeric operations.

Code:

? 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 package com.govindsblog.algos;   public class BinaryToDecimal {       public int getDecimalFromBinary(int binary){                   int decimal = 0;         int power = 0;         while(true){             if(binary == 0){                 break;             } else {                 int tmp = binary%10;                 decimal += tmp*Math.pow(2, power);                 binary = binary/10;                 power++;             }         }         return decimal;     }           public static void main(String a[]){         BinaryToDecimal bd = new BinaryToDecimal();         System.out.println("11 ===> "+bd.getDecimalFromBinary(11));         System.out.println("110 ===> "+bd.getDecimalFromBinary(110));         System.out.println("100110 ===> "+bd.getDecimalFromBinary(100110));     } }

Output:

11 ===> 3 110 ===> 6 100110 ===> 38
