My next little picolisp project... Picolisp's built-in functions for scaled arithmetic are brilliant once you understand how they work. Still, it would be great to get more scientific functions without have to link an external math lib, and get 'real-time' performance when needed as well.
http://wilsonminesco.com/16bitMathTables/ is a nice write-up (link found on hacker news) of what you can do with fixed point, scaling and lookup tables... Also has links to code to generate the tables. I think the concepts and technique will transfer quite nicely to picolisp. We'll see... /Lindsay
