    A base 16 numbering system often used in computer programming.

    Hexadecimal (base 16)_____Decimal (base 10)

    0........................................0
    1........................................1
    2........................................2
    3........................................3
    4........................................4
    5........................................5
    6........................................6
    7........................................7
    8........................................8
    9........................................9
    A......................................10
    B......................................11
    C......................................12
    D......................................13
    E......................................14
    F.......................................15

    Q: Why is this important?
    A: Ever notice that the thumbwheel on a Wybron ColoRAM II color changer reads 0-F? [Actually, it reads 0-C, so I suppose that makes it Base12, as the RAM PSU can control 24 scroller heads.]

    Anyone who deals with MSC or MIDI will get the importance of understanding counting in hex.

    Also some lighting consoles will display "FF" instead of "FL" for a channel's intensity at Full. Why? Hex FF = Dec 255, the maximum DMX value.
