The decimal value of 11001 is 25 Binary to Decimal Example Print("The decimal value of " + str(num) + " is " + str(bin_to_dec(num))) Num = int(input("Enter a binary number: ")) In each loop multiply the multiple with the last bit, divide the number by 10 and multiply the mul variable by 2.

Run a loop until the binary number becomes 0.

This will be used to multiply with the current bit of binary digit.

Define another variable named mul and assign it 1.

Inside this define a variable dec and assign it 0.

Create a python function that takes a decimal number as an integer.

Now we are going to create our own program that converts a binary number to a decimal. In the last method, we used a built-in python function to convert binary to decimal. Print("The decimal value of " + str(num) + " is " + str(dec)) Note: The number to be converted (decimal number here) should be passed as a string. So, we need to pass 2 as the second argument to convert binary to decimal. The int() function takes two arguments, the first is the number to be converted and the second is the base of the number. We can use the int() function to convert binary to decimal.

To convert binary to decimal, we need to multiply each digit with its corresponding power of 2 and add the result. We can convert any binary number to a decimal number. The decimal number system is used in everyday life.

For example, 10, 11, 101, etc.ĭecimal numbers are a base-10 number system. The binary number system is used in computers and other digital devices. We will create custom functions to convert binary to decimal with different approaches.īinary numbers are a base-2 number system. In this article, we will learn how to convert binary to decimal in Python.
