- From the introduction to the manual:
-
- "Calc" is an advanced calculator and mathematical tool that runs as
- part of the GNU Emacs environment. Very roughly based on the HP-28/48
- series of calculators, its many features include:
-
- * Choice of algebraic or RPN (stack-based) entry of calculations.
-
- * Arbitrary precision integers and floating-point numbers.
-
- * Arithmetic on rational numbers, complex numbers (rectangular and
- polar), error forms with standard deviations, open and closed
- intervals, vectors and matrices, dates and times, infinities,
- sets, quantities with units, and algebraic formulas.
-
- * Mathematical operations such as logarithms and trigonometric functions.
-
- * Programmer's features (bitwise operations, non-decimal numbers).
-
- * Financial functions such as future value and internal rate of return.
-
- * Number theoretical features such as prime factorization and
- arithmetic modulo M for any M.
-
- * Algebraic manipulation features, including symbolic calculus.
-
- * Moving data to and from regular editing buffers.
-
- * "Embedded mode" for manipulating Calc formulas and data directly
- inside any editing buffer.
-
- * Graphics using GNUPLOT, a versatile (and free) plotting program.
-
- * Easy programming using keyboard macros, algebraic formulas,
- algebraic rewrite rules, or extended Emacs Lisp.

-
- To install Calc:
-
- 1. Type "uncompress calc-2.02.tar.Z"
-
- 2. Type "tar xvf calc-2.02.tar"
-
- 1,2. Alternatively: "zcat calc-2.02.tar.Z | tar xvf -"
-
- 3. Note that the Calc tar file now creates a "calc-2.02" subdirectory
- of the current directory in which to place its files.
-
- 4. Follow the instructions in the file "INSTALL".
-
-
-
- Calc is written entirely in Emacs Lisp, for maximum portability.
- You do not need to recompile Emacs to install and use Calc.
-
- You will need about six megabytes of disk space to install Calc
- and its Info documentation.
-
- See the file INSTALL for installation instructions. The instructions
- may seem long, but on typical systems you will only need to follow the
- steps shown in the first section.
-
- Don't even try to run Calc in uncompiled (.el) form! It's far too slow.
-
-
- I am anxious to hear about your experiences using Calc. Send mail to
- "daveg@synaptics.com". A bug report is most useful if you include the
- exact input and output that occurred, any modes in effect (such as the
- current precision), and so on. If you find Calc is difficult to operate
- in any way, or if you have other suggestions, don't hesitate to let me
- know. If you find errors (including simple typos) in the manual, let
- me know. Even if you find no bugs at all I would love to hear your
- opinions.
-
- The latest Calc tar files and patches are always available for anonymous
- FTP on prep.ai.mit.edu.

- Thanks,

- Summary of changes to "Calc"
- ------- -- ------- -- ----
-
-
- Version 2.02c:
-
- * Patch to port Calc to Lucid Emacs 19; still works with GNU 18 and GNU 19.
-
- * Fixed a bug that broke `C-x C-c' after Calc graphics had been used.
-
-
- Version 2.02b:
-
- * Minor patch to port Calc to GNU Emacs 19. Will be superseded by Calc 3.00.
-
-
- Version 2.02:
-
- * Revamped the manual a bit; rearranged some sections.
-
- * Added marginal notes for Key/Function Index refs in printed manual.
-
- * Changed `M-# r' to deal more gracefully with blank lines.
-
- * Made reductions like `V R +' and `M-# :' considerably faster.
-
- * Improved parsing and display of cases like "[a + b]".
-
- * Added `t +' and `t -' for doing business date arithmetic.
-
- * Added "syntax tables," the opposite of compositions.
-
- * Added another Rewrites Tutorial exercise.
-
- * Added the "vmatches" function.
-
- * Added the `Modes' variable and `m g' command.
-
- * Improved `u s' to cancel, e.g., "11 mph hr / yd" to get a number.
-
- * Added "quick units" commands "u 0" through "u 9".
-
- * Moved `M-%' to calc.el to avoid autoloading problems.
-
- * Added `M-=' during algebraic entry, acts like `RET ='.
-
- * Made `LFD' prevent evaluation when finishing a calc-edit command.
-
- * Changed calc-store commands to use `t .' mode for trail display.
-
- * Improved integrator to understand forms involving "erf".
-
- * Fixed parser to make sense of "[1....1e2]" input.
-
- * Fixed FORTRAN parser to treat a(i,j) as a_i_j if a is declared matrix.
-
- * Got rid of some version number stamps to reduce size of patches.
-
- * Fixed a bug in defmath treating "<=" and ">=" predicates.
-
- * Fixed a bug in which Calc crashed multiplying two date forms.
-
- * Fixed a bug in line breaker that crashed for large, nested formulas.
-
- * Fixed a bug using ` to edit string("foo").
-
- * Fixed a bug where `M-# y' in Big mode copied stack level number.
-
- * Fixed a bug where `g O' used wrong default directory, no completion.
-
- * Fixed a bug where "foo_bar(i)" parsed in C mode but showed as foo#bar.
-
- * Fixed several bugs where large calculations got "computation too long."
-
-
- Version 2.01:
-
- * Added percentage commands `M-%', `b %', and `c %'.
-
- * Changed Big mode to force radix-10 in superscripts.
-
- * Improved display of fractions in various language modes.
-
- * Changed `a n' to work properly with equations and inequalities.
-
- * The problem with cross references to Index nodes in TeX has been fixed.
-
- * Fixed a bug where recursive esc-maps make calc-ext/-aent unloadable.
-
- * Fixed a bug in `M-# k', then `OFF' right away, with fresh Emacs.
-
- * Fixed a bug in which "S_i_j" was formatted wrong after `j s'.
-
- * Fixed a bug in which `h k u c' positioned cursor on wrong line.
-
- * Fixed a bug where `z ?' crashed if `z %' was defined.
-
- * Fixed a bug in `j O' (calc-select-once-maybe).
-
- * Fixed "make private" not to ask "Delete excess versions" and crash.
-
-
- Version 2.00:
-
- * First complete posting of Calc since 1.01.
-
- * Most parts of Calc have seen changes since version 1.07. See
- section "New for Calc 2.00" in the manual for a summary. In
- the FTP version of the Calc distribution, the file README.prev
- contains a detailed change history from 1.00 up to 2.00.
