| What are Hexadecimal Numbers (Hex Numbers) Us humans
usually count to ten, then start over with eleven, this is probably due to
having ten fingers, and it is called decimal, The problem with this system
with computers is that they work with (binary numbers), Binary numbers are a
switch of either off (0) or on (1), the most easily converted numbers from
and to binary, are the ones that comply with 2 to the power X, for example
Octal is where you count to 7 and then 10(oct), 8 is
(2 to the power 3).
Hexadecimal is the system where we count to 15 (0 - 15 makes 16 numbers),
But since we do not have a one number for a ten, we assign that number the
symbol A, and 11 the symbol B, and to 15 The symbol F

So from the table above, you will notice that 20 in decimal is
equivalent to 14 in hexadecimal, and 23 to 17
For a more thorough understanding, you should look for methods of
converting between systems, and how weight is assigned to every digit of
every number position in every system, You can find that here if you check
soon (when we get the time to write a complete page) or look elsewhere, the
internet is full of information on numbering systems. |
