I had an exam last night - it was worth 45% of the paper I'm working on and I got 100%
It was on Binary, Octal and Hexadeciaml numbers. Converting between them and decimal and back again. Adding them, subtracting them. It also had mantessas and exponents. (which is a computerised shorthand of reducing large numbers to two 8 digit binary numbers rather than one 2000 digit binary number).
I asked the tutor, in todays computing industry why do we need to know this? Her reply was, that Hex is used for colours, and if you go deep into machine coding, but otherwise she teaches it because it is in the handed down prescription and she has to.
So yay... I get to feel proud about knowing, very well, some overall useless stuff.
