17 | From the introduction to the manual: | |
18 | ||
19 | "Calc" is an advanced calculator and mathematical tool that runs as | |
20 | part of the GNU Emacs environment. Very roughly based on the HP-28/48 | |
21 | series of calculators, its many features include: | |
22 | ||
23 | * Choice of algebraic or RPN (stack-based) entry of calculations. | |
24 | ||
25 | * Arbitrary precision integers and floating-point numbers. | |
26 | ||
27 | * Arithmetic on rational numbers, complex numbers (rectangular and | |
28 | polar), error forms with standard deviations, open and closed | |
29 | intervals, vectors and matrices, dates and times, infinities, | |
30 | sets, quantities with units, and algebraic formulas. | |
31 | ||
32 | * Mathematical operations such as logarithms and trigonometric functions. | |
33 | ||
34 | * Programmer's features (bitwise operations, non-decimal numbers). | |
35 | ||
36 | * Financial functions such as future value and internal rate of return. | |
37 | ||
38 | * Number theoretical features such as prime factorization and | |
39 | arithmetic modulo M for any M. | |
40 | ||
41 | * Algebraic manipulation features, including symbolic calculus. | |
42 | ||
43 | * Moving data to and from regular editing buffers. | |
44 | ||
45 | * "Embedded mode" for manipulating Calc formulas and data directly | |
46 | inside any editing buffer. | |
47 | ||
48 | * Graphics using GNUPLOT, a versatile (and free) plotting program. | |
49 | ||
50 | * Easy programming using keyboard macros, algebraic formulas, | |
51 | algebraic rewrite rules, or extended Emacs Lisp. | |
52 | ||

54 | Calc is written entirely in Emacs Lisp, for maximum portability. |
55 | You do not need to recompile Emacs to install and use Calc. | |
56 | ||
57 | You will need about six megabytes of disk space to install Calc | |
58 | and its Info documentation. | |
59 | ||
60 | See the file INSTALL for installation instructions. The instructions | |
61 | may seem long, but on typical systems you will only need to follow the | |
62 | steps shown in the first section. | |
63 | ||
64 | Don't even try to run Calc in uncompiled (.el) form! It's far too slow. | |
65 | ||
66 | ||
67 | I am anxious to hear about your experiences using Calc. Send mail to | |
68 | "daveg@synaptics.com". A bug report is most useful if you include the | |
69 | exact input and output that occurred, any modes in effect (such as the | |
70 | current precision), and so on. If you find Calc is difficult to operate | |
71 | in any way, or if you have other suggestions, don't hesitate to let me | |
72 | know. If you find errors (including simple typos) in the manual, let | |
73 | me know. Even if you find no bugs at all I would love to hear your | |
74 | opinions. | |
75 | ||
76 | The latest Calc tar files and patches are always available for anonymous | |
77 | FTP on prep.ai.mit.edu. | |
78 | ||
79 | Thanks, | |

151 | ||
152 | * Moved `M-%' to calc.el to avoid autoloading problems. | |
