In a lot of source code i've seen i've noticed that most authors use a lot of hex numbers in their work. What i want to know is, why hex? I've been programming for a little over a year so i'm familiar with what it is and HOW to use it, but WHY? I've heard that it's faster than decimal because it's a power of 2 (2^4) but in modern day compilers does that really make a difference?
Thanks.
Hexadecimal numbers are numbers with base 16 and they are in many cases used since conversion from binary number to hexadecimal number is very easy.

Dutch mathematics, 0 == 1. :-)

1111 = 10
Can't tell Shiro's a programmer - he can't decide whether to start counting with 0 or 1 :D

Well, it is very confusing. I once went to the store around the corner to buy some apples. Counting, 0, 1, 2, 3. So I told the girl in the store that I had 3 apples, she didn't believe me.
