Hello, I am trying to understand something about PicoLisp and Fixpoint numbers.

`I am writing an app and would consider PicoLisp should I get my head`

`around Lisp. But I do not understand how to use numbers.`

`I use a lot of floating point numbers and lots of calculations. From`

`simple experiments it seems that the numbers and math appear to be`

`accurate and correct. However I have no understanding of how to present`

`a final result formatted correctly.`

Example: (setq *Scl 5) ;; or could be 10 ... (* 0.00009 0.0009) -> 81 From another language: 0.0000000081 or: (setq *Scl 20) (* 9.9 9.789 9.56789) -> 927234744579000000000000000000000000000000000000000000000000000

`From another language 20 decimal points printed after converting to`

`floating point:`

927.23474457900010747835

`The math looks fine as far as these simple examples go. But if I do`

`several to dozens of different calculations with floating point numbers`

`with unknown values until streamed to the app from some source. How do I`

`know where the decimal point really belongs in order to format correctly`

`for human use? Is it possible?`

`I personally do not have a problem with fixpoint for internal use, as`

`that is simply an implementation issue. However I do need to convert`

`back to the best floating point representation for display or storage.`

Any help in understanding would be greatly appreciated. Thanks. Jimmie -- UNSUBSCRIBE: mailto:picolisp@software-lab.de?subject=Unsubscribe
