Image Courtesy: Pexels Let's explore few different number systems that are in use today and see how with simple three rules, we can build any number system we want. In mathematics, a "base" or a "radix" is the number of different digits or combination of digits and letters that a system of counting uses to represent numbers. ~Wiki~ For example, Base 10 ( Decimal) — Represent any number using 10 digits [0–9] Base 2 ( Binary) — Represent any number using 2 digits [0–1] Base 8 ( Octal) — Represent any number using 8 digits [0–7] Base 16 (Hexadecimal) — Represent any number using 10 digits and 6 characters [0–9, A, B, C, D, E, F] In any of the number systems mentioned above, zero is very important as a place-holding value. Take the number 1005. How do we write that number so that we know that there are no tens and hundreds in the number? We can't write it as 15 because that's a different number and how do we write a million (1, 000, 000) or a billion (1, 000, 000, 000) without zeros? Do you realize it's significance?

Solved Examples Question 1: What is the equivalent form of F2 16? Solution F2 16 = ( F × 161) + ( 2 × 160) = F × 16 + 2 × 1 = 17 × 16 + 2 = 272 + 2 F2 16 = 272 (Decimal form) 8 272 8 34 ---- 0 8 4 ---- 2 4 ---- 4 The octal number is 420 8. Therefore, F2 16 = 420 8.

$\begingroup$ There has been a similar question before: How to convert a hexadecimal number to an octal number? But, in my case I need an Algorithm to directly convert a number from Octal to Hexadecimal and back without converting it to binary/decimal as an intermediate step. Is it possible? asked Jan 15 '14 at 13:58 $\endgroup$ Use octal digits as hexadecimal ones and then just add the numbers you got with weights of $8^n$, working in hexadecimal. For example: consider $a=347_8$. To get a hexadecimal representation without resorting to binary or decimal, you can use the fact that $8<16$, i. e. just take the digits as they are. Now you just do the computation: $$\text{hex}(a)=7\cdot 8^0+4\cdot 8^1+3\cdot 8^2=7_{16}+20_{16}+\text{C}0_{16}=\text{E}7_{16}. $$ Keep in mind that you have to do the multiplication and addition in hexadecimal to fullfill your requirements to not leave hex/oct representation. answered Jan 15 '14 at 14:07 Ruslan Ruslan 5, 930 2 gold badges 18 silver badges 43 bronze badges $\begingroup$ Using binary representation as an intermediate step really saves you a lot of computation.

Program to Convert Hexadecimal to Octal Given a Hexadecimal number, the task is to convert it into an Octal number. Examples: Input: Hexadecimal = 1AC Output: Binary = 0654 Explanation: Equivalent binary value of 1: 0001 Equivalent binary value of A: 1010 Equivalent binary value of C: 1100 Grouping in terms of 3: 000 110 101 100 Equivalent octal value of 000: 0 Equivalent octal value of 110: 6 Equivalent octal value of 101: 5 Equivalent octal value of 100: 4 Input: Hexadecimal = 5D1F Output: Octal = 56437 Approach: A hexadecimal number is a positional numeral system with a radix, or base, of 16 and uses sixteen distinct symbols. An octal number or oct for short is the base-8 number and uses the digits 0 to 7. Octal numerals can be made from binary numerals by grouping consecutive binary digits into groups of three (starting from the right). Steps of Conversion Find the equivalent binary number for each digit of the given hexadecimal number. Add 0's to the left if any of the binary equivalents is shorter than 4 bits.
