Python Code to Convert Decimal to Binary Using Recursion

In this program, you will learn to convert decimal number to binary using recursive function.


Decimal number is converted into binary by dividing the number successively by 2 and printing the remainder in reverse order.

How to convert decimal to binary?

Source Code

# Function to print binary number using recursion
def convertToBinary(n):
   if n > 1:
       convertToBinary(n//2)
   print(n % 2,end = '')

# decimal number
dec = 34

convertToBinary(dec)
print()

Output

100010

This program works only for whole numbers. It doesn’t work for real numbers having fractional values such as: 25.545.64 and so on. We encourage you to create Python program that converts decimal numbers to binary for all real numbers on your own.
