Conversion list for Binary, Octal, Hexadecimal and Decimal Numbers

As its base implies, this number system uses sixteen symbols to represent numbers. If you remember how we dissected the numbers above, we used powers, such as 2 4and ended up with a number we understand. We can determine the value of numbers in this way. Then look at the values. Find Factorial of Number Using Recursion. Base Converter A German merchant of the fifteenth century asked an eminent professor where he should send his son for a good business education.


When we count up from zero in binary, we run out of symbols much more frequently. Please note that the number of digits in any base also called radix N is exactly the same number N. We want to know what this number is in decimal so that we can understand it better.

Watch headings for an “edit” link when available. Once you know how to do that in the decimal system, you are supposed to know how to handle the same thing in other bases.

Number conversion

We simply repeat the process until the p becomes a zero. Doing this makes p become 7. Find Hash of File. The third digit from the right in binary only represented converzionwhich is 4. In the same way that forwe say there is one group oftwo groups of 10, and three groups of 1, for octal and the numberthere are three groups of 64, six groups hexadecima 8, and four groups of 1. The bits switch on and off following their value.

We are going to go through this one step at a time. However, when you reach 9, you go directly to A. That’s a lot of apples. You count further until you reach The number has three digits, so starting from the right, we have position 0, position 1, and position 2.


Binary, hexadecimal, and octal refer to different number systems. Another device permits the user to specify the bases of conversion. To understand this example, you should have the knowledge of following Python programming topics: So after F is So, V will now beor Now, what about greater numbers?

Number systems are used to describe the quantity of something or represent certain information. When we count up one from the 7, we need a new placement to represent what we call 8 since an 8 doesn’t exist in Octal. B stands for the decimal 11 in any number system with base greater than 11, and so on.

Python Program to Convert Decimal to Binary, Octal and Hexadecimal

Check out these related Python examples: The hexadecimal system is Base Sixteen. A number with the prefix ‘0b’ is considered binary, ‘0o’ is considered octal and ‘0x’ as hexadecimal.

There isn’t really a good formula for this, but there is an algorithm that you can follow which will help accomplish what we want. So, after 7 is Expansion of Integers in an Integer Base.
