Using Hexadecimal Numbers to Represent Binary Numbers

As you can see from the previous post, binary numbers can become rather long. With only two possible values, 0 and 1, it takes 16 binary digits to represent the decimal value +32,768. For that reason, the hexadecimal, or base 16, system is often used as a shorthand representation of binary numbers. The hexadecimal system uses 16 digits: 0 to 9 and A to F. The letters A to F represent the values 10, 11, 12, 13, 14, and 15.

The maximum value that can be represented in four binary digits is 2⁴ − 1, or 15. The maximum value of a hexadecimal digit is also 15, which is represented by the letter F. So you can reduce the size of a binary number by using hexadecimal digits to represent each group of four binary digits.

Here are displayed the hexadecimal digits along with their binary equivalents.

In case I have to point it out to you, I am the Buddha. He had the 32 physical characteristics which signified the 32 Kabbalistic paths of wisdom.

Every post I made was genius without my intention.
