Hexadecimal..........................God knows what that means!!!!!!!!!!!!!!

02/02/07

Welcome to February! This is my first official post of this new month! Today we learned about Hexadecimal. Hexadecimal is a number system just like the binary number system just harder.


The difference between the binary number system and the hexadecimal number system is that the binary number system increases by multiplying by 2 and the hexadecimal number system increases by multiplying by 16. This is a lot harder. Down below you can see the three different kinds of number systems: base 10, binary, and hexadecimal.


: Base 10


: Binary

: Hexadecimal

The hexadecimal number system works kind of like the binary number system. For the hexadecima number system you can only put numbers between 1-9 in the columns. For numbers 10-15 you have to use the letters A-F.

A: 10

B: 11

C: 12

D: 13

E: 14

F: 15

For example if you want to place the number 19 then you would put a 1 under 16th column and a 3 under the ones column.

Most people use hexadeciaml to tell the values of RGB which stands for Red, Green and Blue which are the three primary colours. There are 255 levels of each colour. So 255*255*255 gives us 16.7 million combinations of colours.

This just gives me a heart attack. Well that's pretty much what we did today. See you next time!!!!!!!!!!!
