I would recommend to pay a little bit of attention to ADW-CHARTING and VECTO packages. The first is for plotting various charts and the second is for drawing images using vector operations.

I use SBCL on Linux/FreeBSD and CLISP on Windows.

Especially that the ECL had a new release recently.

The http://www.sbcl.org still considers 1.0.18 the latest release!

Thank you all for your help.

The approach with modifying default float format does work for me.

Thanks

Hello, What is the proper way to read (parse) real numbers in Common Lisp? The problem is, that I have to read relatively large real numbers, and both SBCL and CLISP fail: [4]> (- (read-from-string "1169991858.90605") 1169991859.32605) 0.0 [5]> (- (read-from-string "1169991858.90605&q...

Some time before I've used the data from the survey and put a reference in the Коммон Лісп article on Ukrainian Wikipedia about Common Lisp.

Thanks for your work!

Thanks everybody for helping me. It seems that the issue becomes more clear to me. As far as I understood, the vectors I pass to functions are not copied, instead, references are passed. I have also conducted a very simple test: CL-USER> (setq a (make-sequence '(vector float) 3 :initial-element 0)) ...

But I am not sure if this has anything to do with your question. Actually, I am trying to parse CSV files stored in GZIP archives, calculate simple statistics and output results. The calculations are simple (like computing mean value over some samples) and, generally speaking, could be made in cons...

Hello, I would like to ask whether it is possible to pass parameters to functions by reference ? As far as I understand, function call parameters (even vectors, sequences, etc.) are passed by value (the form is evaluated, yielding the vector, sequence, etc. and the value is passed as a function para...
