Original question: Is it possible that the evaluation of ((x-1)/(x+1))+((x+1)/(x-1))=> returns ((x-1)/(x+1))+((x+1)/(x-1))=>(2 x^2 + 2) / (x^2 - 1) The calc function nrat transforms its expression … You can try nrat(((x-1)/(x+1))+((x+1)/(x-1))) with M-: (calc-eval "nrat(((x-1)/(x+1))+((x+1)/(x-1)))") The result is: (2*x^2 + 2) / (x^2 - 1) If you prefer to work with the Calc stack you can put ( …

See the Calc manual on calc-substitute. … Quote: The ‘a b’ (‘calc-substitute’) [‘subst’] command substitutes all occurrences of some variable or sub-expression of an expression with a new sub-expression. …

The extension (not as a package but as code): (require 'calc) (require 'calc-aent) (require 'calc-units) (defun calc-do-alg-entry-completion (fun &rest args) "Call `calc-do-alg-entry' as FUN with ARGS … " #'calc-aent-complete-word) (advice-add 'calc-do-alg-entry :around #'calc-do-alg-entry-completion) …

You can do that interactively by query-replace-regexp with embedded Elisp in the replacement string. Go to the beginning of the file. Type M-x query-replace-regexp RET. Input {x: \([0-9]+\), y:\([0- …

#x1234 is just a hex number and not a byte-encoding. You can easily define a byte encoding yourself. For an instance with the following my-byte-decode function: (defun my-byte-decode (list) "Decode …

Afterwards you can use the calc-trail-mode bindings to evaluate parts of the read-in calc commands. (defvar-local calc-trail-buffer-file-name nil "Like `buffer-file-name' for calc-trail buffers.") … (push #'calc-trail-save write-contents-functions) (local-set-key (kbd "C-x i") #'calc-insert-file)) (add-hook 'calc-trail-mode-hook #'calc-trail-install-save) …

You can enforce an additional evaluation of calc by simplify: |-----+----+---+-------| | x | -2 | 0 | 3.7 | |-----+----+---+-------| | 2 x | -4 | 0 | 7.4 | | x^2 | 4 | 0 | 13.69 | #+TBLFM: @<<$ …

Looks like you have composed characters (^U is composed to Û). That is usually already controlled by the OS. Just hit the spacebar after typing ^ to get a caret as input character.

Your guess inner is right. The first two operands of inner are the multiplication and the summation operator, respectively. The remaining two arguments are the vectors for the inner product. The summ …

You can write the operation into the first inner calc-eval of the linked answer. … (math-convert-units (calc-eval (concat "12 V * " $4) 'raw) (calc-eval "W" 'raw))) Note that this works with the setting M-x calc-normal-language. …
