However, there is also another alternative method to handle this program through the use of in-built functions. Finally all the bits together are obtained in reverse order, that is why while returning the result we return the reverse of it using the expression.
We keep doing it while n is greater than 0. In the third iteration, the number is divided by 8. First iteration we check the remainder for 2, second iteration we check the remainder for 4 and so on. we run a loop and within the loop we keep on dividing n by 2. We take a number as input, if the number is zero we immediately return 0, however if n is greater than 0. The logic is based upon the earlier even or odd logic, and remainder concept. N=int(input("Enter decimal number to convert into binary value : "))Įnter decimal number to convert into binary value : 6 We can quickly check based on this condition by remainder of 2 (If n%2=0, then the number is even). For example, we can easily find out what would be the last bit if the number is even then the last bit would be zero and if the number is odd, the last bit is going to be 1.
Writing a program to handle conversion of Decimal to Binary in Pythonįor an efficient solution to the problem, the idea is to start from the lowest power rather than the highest power because it would be easier to find out the values for lower powers. The highest factor greater than or equal to 4 is 4, so we write it as 8+4. Once we subtract 8 from 12, we obtain 4 as the value. If we take 12, : 1/8 and 1/4, 0/2 and 0/1 the highest number less than or equal is 8. So we write 16 first and then subtract 16 from 17 to get the remaining number as 1. 16 would be the highest, beyond 16 it would be 32 which would be higher than 17. If we are given the number 17, let us consider the powers of 2: 1/ 16, 0/8, 0/4, 0/2. First we find out if the highest power of 2, whether it is smaller or equal to the given number. Let us discuss a naïve solution to solve the problem, and this is the solution we use in our minds to convert decimal numbers to binary. Any number can be expressed through Fibonacci sequence digits. The powers of 2 are a complete sequence, another example of complete sequence is Fibonacci sequence. If we are given 0 as input however, we can simply write 0 as output. We can write any decimal as sum of powers of two.
It is important for us to understand the decimal to binary conversion process. What is binary value? Our computer stores and processes everything in the form of binary and in the binary all data is expressed in either 0 or 1. The result should be stored in a string for convenience. We are given a non-negative integer, our task is to write a function that takes the integer as an argument and then returns the binary value. In the previous article we discussed how a string can be reversed, now let us explore number system conversions in Python.
