Calc: mend math-nth-root-float (bug#51209)

2021-10-15T10:14:05+00:00

Reported by Iñaki Cornejo.

* lisp/calc/calc-math.el (math-nth-root-float):
Fix old refactoring mistake.
* test/lisp/calc/calc-tests.el (calc-nth-root): New test.

; Minor stylistic checkdoc fixes in test/**/*.el

Calc: control digits after decimal point (bug#47302)

2021-04-27T16:10:01+00:00

Calc normally displays a trailing decimal point for floats with no
fractional part, like '12.'. Some uses require at least one digit
after the point; add the governing variable calc-digit-after-point.

* lisp/calc/calc.el (calc-digit-after-point): New variable.
(math-format-number): Use it.
* test/lisp/calc/calc-tests.el (calc-display-digit-after-point):
New test.

Fix multiple Calc defmath errors (bug#46750)

2021-03-01T19:59:52+00:00

Fix incorrect variable scoping in `let*`, `for` and `foreach`.
Fix loop variable value in `foreach` (should be element, not tail).
Fix function quoting, as in ('cons x y) -- didn't work at all.

Reported by Stephan Neuhaus.

* lisp/calc/calc-prog.el (math-define-exp, math-handle-foreach):
* test/lisp/calc/calc-tests.el: (var-g, test1, test2, test3, test4)
(test5, test6, test7, calc-defmath): Test various defmath forms.

Calc: allow infinite binary word size (bug#43764)

2020-10-13T09:29:01+00:00

Setting the word size ("b w") to 0 removes the word size clipping for
all bit operations (effectively as if a word size of -∞ had been set).
Rotation is disallowed; logical and arithmetic shifts behave
identically.

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 mode

2020-10-13T09:29:01+00:00

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.

Calc: make tests less chatty

2020-10-13T09:17:35+00:00

* test/lisp/calc/calc-tests.el (calc-extract-units, calc-convert-units)
(calc-matrix-determinant, calc-choose): Remove "Working..." messages.
(calc-tests--check-choose, calc-tests--explain-choose): Eliminate.

Improve coverage of Calc bit shift test

2020-10-10T09:29:43+00:00

* test/lisp/calc/calc-tests.el (calc-tests--rsh, calc-tests--rash)
(calc-shift-binary): Test with negative word sizes.

Calc: fix arithmetic right shift sign bit detection

2020-10-09T09:24:15+00:00

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.
