    Bullshit. Half the time I google, I spend a SIGNIFICANT amount of time
    sifting through the results looking for the gold specks in a bunch of
    dirt, and often they aren't there.

    Randy,

    If you're having trouble finding things with search engines, you could try
    Googling for "How to google". In this industry, if you can't work a search
    engine, you're in big trouble.

    If you can't be arsed to do that, here's a link. ;-)

    p.s. To the OP, I replied on C.A.F.

    You're both right.
    Google *CAN* be useful.
    Google is often a *PAIN*!!!!
    And you can't be sure which it will be until _after_ the search.

    I've made a semi-hobby of outsmarting Google for the last 18 months.
    One thing I've learned is precede all search terms with "allintext:" .
    That limits hits to pages with search term in body of page. Otherwise
    some hits will be to pages which make a reference to pages which contain
    the search term. The art comes in choosing optimum boolean expression to
    get what you really want

    Well, thanks Ken. I'm not pissed off, just expressing an opinion.

    1QN seems to mean fractional two's complement in some proprietary
    context.

    The OP should use more standard terminology. Participants shouldn't
    have to google stuff like this up.

    I thought that was fairly standard terminology

    Q15 == no integer part and 15 bits of fraction
    Q31 == no integer part and 31 bits of fraction
    1Q14 == 1 integer bit and 14 bits of fraction
    1QN == 1 integer bit and all the remaining bits (however many they may
    be) are fraction

    All these kinda assume there is a sign bit as well. People don't often
    express unsigned fixed point in this way. I wonder what might be
    consider the appropriate shorthand way to say "no sign, no integer
    part and 16 bits of fraction"?

    Steve
