Now you are getting the idea, Stein Vidar. This is a MUCH
better solution than this wimpy solution by Martin Leuthi:

function alog2, x
return, alog(x)/alog(2.0)
end

MUCH more billable and difficult! Are you looking for
a job? I like your style. :-)

Cheers,

David

P.S. In case there is any doubt whatsoever in anyone's
mind, I am just kidding Stein Vidar. As anyone who has
written any kind of program at all knows, it is damn
difficult sometimes to see the simple solutions first.
My first attempt to solve this problem was along the
lines of Amara's, only much, much worse. :-(

Thanks to Martin and Med Bennett for putting us right.
And to Stein Vidar for giving us another of his excellent
examples of well-written DLMs. :-)
