Day 73: Convert Binary to Decimal Number of 100DaysCodingChallenge

Hello all, 

#day73 

Day73 

Today's my task was to Write a Program to Convert Binary to Decimal number manually by creating user-defined functions.

I have started the 100 days of coding challenge to improve my programming skills..

Code : 

// JavaScript program to convert binary to decimal
 
// Function to convert binary to decimal

function binaryToDecimal(n)
{
    let num = n;
    let dec_value = 0;
    // Initializing base value to 1, i.e 2^0
    let base = 1;
    let temp = num;
    while (temp) {
        let last_digit = temp % 10;
        temp = Math.floor(temp / 10);
        dec_value += last_digit * base;
        base = base * 2;
    }
    return dec_value;
}

// Driver program to test above function
    //let num = 10101001;
    let num = prompt("Enter a number : ");
    console.log("The Decimal Number is ", binaryToDecimal(num) + " ");
// This code

Output :     

 

Happy Coding:)
