15 | From the introduction to the manual: | |
16 | ||
17 | "Calc" is an advanced calculator and mathematical tool that runs as | |
18 | part of the GNU Emacs environment. Very roughly based on the HP-28/48 | |
19 | series of calculators, its many features include: | |
20 | ||
21 | * Choice of algebraic or RPN (stack-based) entry of calculations. | |
22 | ||
23 | * Arbitrary precision integers and floating-point numbers. | |
24 | ||
25 | * Arithmetic on rational numbers, complex numbers (rectangular and | |
26 | polar), error forms with standard deviations, open and closed | |
27 | intervals, vectors and matrices, dates and times, infinities, | |
28 | sets, quantities with units, and algebraic formulas. | |
29 | ||
30 | * Mathematical operations such as logarithms and trigonometric functions. | |
31 | ||
32 | * Programmer's features (bitwise operations, non-decimal numbers). | |
33 | ||
34 | * Financial functions such as future value and internal rate of return. | |
35 | ||
36 | * Number theoretical features such as prime factorization and | |
37 | arithmetic modulo M for any M. | |
38 | ||
39 | * Algebraic manipulation features, including symbolic calculus. | |
40 | ||
41 | * Moving data to and from regular editing buffers. | |
42 | ||
43 | * "Embedded mode" for manipulating Calc formulas and data directly | |
44 | inside any editing buffer. | |
45 | ||
46 | * Graphics using GNUPLOT, a versatile (and free) plotting program. | |
47 | ||
48 | * Easy programming using keyboard macros, algebraic formulas, | |
49 | algebraic rewrite rules, or extended Emacs Lisp. | |
50 | ||
51 | ||
52 | ||
53 | ||
54 | To install Calc: | |
55 | ||
56 | 1. Type "uncompress calc-2.02.tar.Z" | |
57 | ||
58 | 2. Type "tar xvf calc-2.02.tar" | |
59 | ||
60 | 1,2. Alternatively: "zcat calc-2.02.tar.Z | tar xvf -" | |
61 | ||
62 | 3. Note that the Calc tar file now creates a "calc-2.02" subdirectory | |
63 | of the current directory in which to place its files. | |
64 | ||
65 | 4. Follow the instructions in the file "INSTALL". | |
66 | ||
67 | ||
68 | ||
69 | Calc is written entirely in Emacs Lisp, for maximum portability. | |
70 | You do not need to recompile Emacs to install and use Calc. | |
71 | ||
72 | You will need about six megabytes of disk space to install Calc | |
73 | and its Info documentation. | |
74 | ||
75 | See the file INSTALL for installation instructions. The instructions | |
76 | may seem long, but on typical systems you will only need to follow the | |
77 | steps shown in the first section. | |
78 | ||
79 | Don't even try to run Calc in uncompiled (.el) form! It's far too slow. | |
80 | ||
81 | ||
82 | I am anxious to hear about your experiences using Calc. Send mail to | |
83 | "daveg@synaptics.com". A bug report is most useful if you include the | |
84 | exact input and output that occurred, any modes in effect (such as the | |
85 | current precision), and so on. If you find Calc is difficult to operate | |
86 | in any way, or if you have other suggestions, don't hesitate to let me | |
87 | know. If you find errors (including simple typos) in the manual, let | |
88 | me know. Even if you find no bugs at all I would love to hear your | |
89 | opinions. | |
90 | ||
91 | The latest Calc tar files and patches are always available for anonymous | |
92 | FTP on prep.ai.mit.edu. | |
93 | ||
94 | Thanks, | |
