Hi
 There was a talk at our last svfig ( Silicon Valley Forth Interest Group )
about how to find the interesting integer ratios ( like 355/113 ). Although,
one can simply try all kinds of numbers ( quite quick on todays processors ),
there are algorithms based on number theory that are faster. I wish I was
paying more attention so I could pass on what was done.
 The talk was based on creating speciallized languages to handle these
interesting problems of LSD's ( Least Common Denominator ). The fellow
that gave the talk was named LaFarr. Forth is especially adapt at
creating application oriented languages. I fact that is the way
one normally programs in Forth, once they know what they are doing.
