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.
