Hexadecimal 30

In computing hexadecimal is used to represent bytes. Zero through to 9 then A, B, C, D, E, F are used to count to 15 when working in hexadecimal (also known as base 16). So, 15 can be represented by four bits which is half a byte (also known as a nibble). You with me so far? If you want to count above 15 then you go up to a whole byte and use the same principal, therefore say 20 ( in our common way of counting i.e. base 10 ) is 14 hexadecimal. A byte can therefore hold 256 values (0-255). 255 is FF hex. Today, I am 48 years old or hexadecimal 30! I don’t really like either base, it’s still a big number. So I think I’m going to stick to my counting scheme of last year whilst touring Espana. Then I was 2.35, now I'm am 2.4 - Dave’s that is. Hasta Luego.
