About Number Systems

Octal System

The octal numeral system, or oct for short, is the base-8 number system, 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).

Hexadecimal System

The hexadecimal numeral system, or hex for short, is a base-16 number system that uses the digits 0-9 and the letters A-F to represent values 10-15. Hexadecimal is commonly used in computing and digital electronics because it provides a more human-friendly representation of binary-coded values.

Conversion Process

Converting from octal to hexadecimal involves two main steps:

  1. Convert each octal digit to its 3-bit binary equivalent.
  2. Group the resulting binary digits into sets of four (starting from the right), and convert each group to its hexadecimal equivalent.

Example: Convert Octal "75" to Hexadecimal

Step 1: Convert each octal digit to 3-bit binary:

7 → 111

5 → 101

Step 2: Combine the binary digits:

111 101

Step 3: Group binary digits into sets of four (from right):

0011 1101

Step 4: Convert each 4-bit group to hexadecimal:

0011 → 3

1101 → D
