You've no idea how many 'doh!' moments I've had with that chip - finding that there's always some better way and I've been doing it wrong all along :)
The trick above is actually most useful for shifting - less for arithmetic. e.g. if you want a table of shift coefficients which includes a shift of 0, it can be done with a signed mul and -ve table coefficients. Otherwise it just becomes a painful special case.

What's the anti-troll code?
That's your personal code to be able to add comments and messages on the dhs.nu site.
Don't have a code or forgot it? Fix it here.
