Subject: help with ratio/vector algorithm

...

ratio r = 2^p * 3^q

if q < 0
then p = int((log(3^abs(q)) / log(2)) + 0.5)
else p = (int((log(3^abs(q)) / log(2)) + 1.5)) * -1
end if

Why not just have a list n^m/d where d = 2^int(log(n^m)/log(2)) and a list
n/d^m where n = 2^(int(log(d^m)/log(2))+1) That's is what I use. But I
don't think I understand what you're trying to do.

thanks for the suggestions on that topic, but Graham
has already given me the solution which works correctly:

mod((log(3^abs(q))/log(2)),1) - (log(3^abs(q))/log(2))
