Conversion from HEX to DEC
Just for those of you that don't know or that just need a little refresher like me
The simplest way to go from hex to dec is to go to binary first behold the table below!
HEX DEC BINARY
0 0 0000
1 1 0001
2 2 0010
3 3 0011
4 4 0100
5 5 0101
6 6 0110
7 7 0111
8 8 1000
9 9 1001
A 10 1010
B 11 1011
C 12 1100
D 13 1101
E 14 1110
F 15 1111
OH NO I stopped at 15 now what eh?
Ill show ya
Lets take the HEX number 1C8........
Ok, now well take that number and transfer it into binary
1 C 8
0001 1100 1000
Ok now the binary in Dec
0 0 0 1 1 1 0 0 1 0 0 0
^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^
2048 1024 512 256 128 64 32 16 8 4 2 1
So if we add all those little ones and zero's up we get (drum roll please)
456 and if I put that into my little windows calc and convert it into hex I get 1C8
TA DA!
Thanks for reading I hope this can make things a little clearer for hex or worked as a nice refresher,

There's an even easier way:
1C8 -> (1 x 16^2) + (12 x 16^1) + (8 x 16^0) = 456
Far simpler and less prone to errors.

Yea If you have a calculator at your exam, I had to work this crap out by hand it was just easyer for me to do it this way but thanks for the input,

It's hardly difficult to do 16^2 - use long multiplication if you have to. I doubt that you'd have to convert more than 4 hex figures to decimal (e.g. FF6CA).
