* Fix byte-compilation warningsMattias Engdegård2021-09-111-8/+6
| | | | | | | * lisp/calc/calc-graph.el (calc-gnuplot-check-for-errors): * lisp/calendar/holidays.el (list-holidays): Dodge 'save-excursion+set-buffer' warnings that appeared after the progn flattening was introduced.
* Make calc-grab-region work with rectangular selectsLars Ingebrigtsen2021-09-061-1/+4
| | | | | * lisp/calc/calc.el (calc-grab-region): Heed `rectangle-mark-mode' (bug#50403).
* Autoload calc-grab-sum-across and calc-grab-sum-downLars Ingebrigtsen2021-09-011-0/+2
| | | | | | * lisp/calc/calc.el (calc-grab-sum-down): (calc-grab-sum-across): Autoload, since they can be used from outside Calc (bug#50311).
* Make calc plotting through gnuplot work on non-X gnuplotsLars Ingebrigtsen2021-08-311-7/+14
| | | | | | * lisp/calc/calc-graph.el (calc-graph-plot): Fall back on "dumb" if we don't support the terminal (bug#50237). (calc-gnuplot-command): Say whether the command errored out.

After a suggestion by Vincent Belaïche. * lisp/calc/calc-bin.el (calc-word-size, math-binary-arg) (math-binary-modulo-args, calcFunc-lsh, calcFunc-ash, calcFunc-rot) (math-clip, math-format-twos-complement): Allow a word size of 0, meaning -∞. * test/lisp/calc/calc-tests.el (calc-tests--not, calc-tests--and, calc-tests--or, calc-tests--xor) (calc-tests--diff): New functions. (calc-tests--clip, calc-tests--rot, calc-shift-binary): Extend to cover word size 0. (calc-bit-ops): New test. * doc/misc/calc.texi (Binary Functions): Update manual. * etc/NEWS: Announce the change.
* Calc: revert to old precedence of '/' in (La)TeX input modeMattias Engdegård2020-10-131-1/+1
| | | | | | | | Make the '/' precedence higher than that of '+' and '-' again, partially reverting fda9b316f84 (bug#43902). * lisp/calc/calc-lang.el (tex): Change precedence of '/'. * test/lisp/calc/calc-tests.el (calc-latex-input): New test.
* * lisp/calc/: Use lexical scoping in all the filesStefan Monnier2020-10-1039-466/+529
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Includes the following pervasive changes: - Move some defvars earlier in the file so they cover earlier let-bindings - Change dynamically scoped `calc-FOO` or `math-FOO` function arguments to just FOO and then let-bind the `calc-FOO` or `math-FOO` variable explicitly in the body of the function. In some cases, the beginning of the function was changed to refer to FOO so as to delay the binding to a nearby `let` when I could ensure that it did not make a difference. - Add an underscore in front of unused vars or comment them out altogether. - Replace unused `err` arg to `condition-case` with nil. Plus the additional itemized changes below. * lisp/calc/calc-map.el (calcFunc-reducer): * lisp/calc/calc-arith.el (math-setup-declarations): * lisp/calc/calc-help.el (calc-full-help, calc-help-index-entries) (calc-full-help): Use `ignore-errors`. * lisp/calc/calc-embed.el (calc-embedded-modes-change): Declare `the-language` and `the-display-just` as dynamically scoped. * lisp/calc/calc-forms.el (math-setup-year-holidays): Use `dolist`. * lisp/calc/calc-graph.el (calc-graph-set-styles): Use `symbol-value` rather than `eval.` (calc-graph-delete-temps, calc-graph-set-styles): Use ignore-errors. * lisp/calc/calc-macs.el (calc-with-trail-buffer): Add artificial use of `save-buf` to silence compiler warnings in all the cases where `body` doesn't make use of it. * lisp/calc/calc-math.el (math-largest-emacs-expt) (math-smallest-emacs-expt, math-use-emacs-fn): Use ignore-errors. * lisp/calc/calc-mode.el (calc-total-algebraic-mode): Remove "P" from interactive spec since it's not used anyway. * lisp/calc/calc-rewr.el (calc-match): Simplify. * lisp/calc/calc.el (calc-buffer): Give it a global nil value, so it's automatically declared dynbound in any file that requires `calc`. (calcDigit-nondigit): Adjust accordingly. * lisp/calc/calcalg2.el (calcFunc-table): Declare `var-dummy` as dynbound. (math-scan-for-limits): Comment out dead code. * lisp/calc/calcalg3.el (math-general-fit): Declare `var-YVAL` and `var-YVALX` as dynbound.
* Calc: fix arithmetic right shift sign bit detectionMattias Engdegård2020-10-091-1/+1
| | | | | | | | | | | | Arithmetic right shift didn't compute the bit to shift in correctly. For example, #x600000000 right-shifted 8 steps (with 32 bit word size) resulted in #xff000000 rather than 0. (Bug#43764) * lisp/calc/calc-bin.el (calcFunc-ash): Fix condition. * test/lisp/calc/calc-tests.el (calc-tests--clip, calc-tests--lsh) (calc-tests--rsh, calc-tests--ash, calc-tests--rash, calc-tests--rot): New. (calc-shift-binary): New test.
* Calc: fix formatting and parsing Unix time (bug#43759)Mattias Engdegård2020-10-021-4/+9
| | | | | | | | | | | | | The number of days from epoch to Jan 1, 1970 that was used in parsing and formatting Unix time was incorrect. The previous fix (in e368697ce36) was incomplete. Reported by Vincent Belaïche. * lisp/calc/calc-forms.el (math-unix-epoch): New constant. (math-format-date-part, math-parse-standard-date, calcFunc-unixtime): Use math-unix-epoch instead of a constant that is sometimes wrong. * test/lisp/calc/calc-tests.el (calc-unix-date): New test.
* Calc: fix business days calculation (bug43677)Mattias Engdegård2020-10-021-6/+7
| | | | | | | | | | | | | | | | The calculation of business days was broken in 2012 (probably 310e60d9454fe2 or thereabouts) when the date representation changed epoch so that Jan 1, 1 AD became day number 1 instead of 0. Repair this, along with an unrelated bug that prevented arbitrary holiday weekdays from working. Reported by Aaron Zeng. * lisp/calc/calc-forms.el (math-to-business-day) (math-from-business-day): Correct calculation of weekdays using Calc's current (Rata Die) chronology. Modify loop condition to cope with odd sets of holiday weekdays. * test/lisp/calc/calc-tests.el (calc-business-days): New test.

* Use a square root character in calc displaysLars Ingebrigtsen2020-09-151-1/+2
| | | | | | * lisp/calc/calccomp.el (math-compose-sqrt): Use a square root character, if possible (bug#22919). Suggested by Zephyr Pellerin <zephyr.pellerin@gmail.com>.
* Calc: fix binomial coefficients for negative arguments (bug#16999)Mattias Engdegård2020-09-141-13/+29
| | | | | | | | | | | | | | | | | | For some values outside integers 0≤k≤n, (n choose k) gave wrong results, entered infinite recursion or used unreasonably amounts of stack space. This change fixes that and extends the function to all integer arguments using the definitions from M. J. Kronenburg (https://arxiv.org/abs/1105.3689). * lisp/calc/calc-comb.el (calcFunc-choose): Fix sign error to prevent infinite recursion and extend function to handle all integer arguments. (math-choose-iter, math-choose-float-iter): Rewrite in iterative form; no TCO in elisp yet. * test/lisp/calc/calc-tests.el (calc-tests--fac, calc-tests--choose) (calc-tests--check-choose, calc-tests--explain-choose) (calc-tests--calc-to-number): New helper functions. (calc-choose): New test.

* Fix calc tests when running noninteractivelyMattias Engdegård2020-09-111-1/+1
| | | | | | This error was introduced in 8e1376a39125c3ffc0484077b502444d853eca79. * lisp/calc/calc.el (calc--header-line): Prevent size from being negative.
* Use a header line in calc mode instead of a regular in-buffer lineBoruch Baum2020-09-101-15/+32
| | | | | | * lisp/calc/calc.el (calc-trail-here): Use a header line. (calc--header-line): New function. (calc-trail-mode): Use a header line.
