@unnumberedsec Preamble
X
X  The license agreements of most software companies try to keep users
at the mercy of those companies.  By contrast, our General Public
License is intended to guarantee your freedom to share and change free
software---to make sure the software is free for all its users.  The
General Public License applies to the Free Software Foundation's
software and to any other program whose authors commit to using it.
You can use it for your programs, too.
X
X  When we speak of free software, we are referring to freedom, not
price.  Specifically, the General Public License is designed to make
sure that you have the freedom to give away or sell copies of free
software, that you receive source code or can get it if you want it,
that you can change the software or use pieces of it in new free
programs; and that you know you can do these things.
X
X  To protect your rights, we need to make restrictions that forbid
anyone to deny you these rights or to ask you to surrender the rights.
These restrictions translate to certain responsibilities for you if you
distribute copies of the software, or if you modify it.
X
X  For example, if you distribute copies of a such a program, whether
gratis or for a fee, you must give the recipients all the rights that
you have.  You must make sure that they, too, receive or can get the
source code.  And you must tell them their rights.
X
X  We protect your rights with two steps: (1) copyright the software, and
(2) offer you this license which gives you legal permission to copy,
distribute and/or modify the software.
X
X  Also, for each author's protection and ours, we want to make certain
that everyone understands that there is no warranty for this free
software.  If the software is modified by someone else and passed on, we
want its recipients to know that what they have is not the original, so
that any problems introduced by others will not reflect on the original
authors' reputations.
X
X  The precise terms and conditions for copying, distribution and
modification follow.

@center TERMS AND CONDITIONS
@end ifinfo
X
@enumerate
@item
This License Agreement applies to any program or other work which
contains a notice placed by the copyright holder saying it may be
distributed under the terms of this General Public License.  The
``Program'', below, refers to any such program or work, and a ``work based
on the Program'' means either the Program or any work containing the
Program or a portion of it, either verbatim or with modifications.  Each
licensee is addressed as ``you''.
X
@item
You may copy and distribute verbatim copies of the Program's source
code as you receive it, in any medium, provided that you conspicuously and
appropriately publish on each copy an appropriate copyright notice and
disclaimer of warranty; keep intact all the notices that refer to this
General Public License and to the absence of any warranty; and give any
other recipients of the Program a copy of this General Public License
along with the Program.  You may charge a fee for the physical act of
transferring a copy.
X
@item
You may modify your copy or copies of the Program or any portion of
it, and copy and distribute such modifications under the terms of Paragraph
1 above, provided that you also do the following:
X
@itemize @bullet
@item
cause the modified files to carry prominent notices stating that
you changed the files and the date of any change; and
X
@item
cause the whole of any work that you distribute or publish, that
in whole or in part contains the Program or any part thereof, either
with or without modifications, to be licensed at no charge to all
third parties under the terms of this General Public License (except
that you may choose to grant warranty protection to some or all
third parties, at your option).
X
@item
If the modified program normally reads commands interactively when
run, you must cause it, when started running for such interactive use
in the simplest and most usual way, to print or display an
announcement including an appropriate copyright notice and a notice
that there is no warranty (or else, saying that you provide a
warranty) and that users may redistribute the program under these
conditions, and telling the user how to view a copy of this General
Public License.
X
@item
You may charge a fee for the physical act of transferring a
copy, and you may at your option offer warranty protection in
exchange for a fee.
@end itemize
X
Mere aggregation of another independent work with the Program (or its
derivative) on a volume of a storage or distribution medium does not bring
the other work under the scope of these terms.
X
@item
You may copy and distribute the Program (or a portion or derivative of
it, under Paragraph 2) in object code or executable form under the terms of
Paragraphs 1 and 2 above provided that you also do one of the following:
X
@itemize @bullet
@item
accompany it with the complete corresponding machine-readable
source code, which must be distributed under the terms of
Paragraphs 1 and 2 above; or,
X
@item
accompany it with a written offer, valid for at least three
years, to give any third party free (except for a nominal charge
for the cost of distribution) a complete machine-readable copy of the
corresponding source code, to be distributed under the terms of
Paragraphs 1 and 2 above; or,
X
@item
accompany it with the information you received as to where the
corresponding source code may be obtained.  (This alternative is
allowed only for noncommercial distribution and only if you
received the program in object code or executable form alone.)
@end itemize
X
Source code for a work means the preferred form of the work for making
modifications to it.  For an executable file, complete source code means
all the source code for all modules it contains; but, as a special
exception, it need not include source code for modules which are standard
libraries that accompany the operating system on which the executable
file runs, or for standard header files or definitions files that
accompany that operating system.
X
@item
You may not copy, modify, sublicense, distribute or transfer the
Program except as expressly provided under this General Public License.
Any attempt otherwise to copy, modify, sublicense, distribute or transfer
the Program is void, and will automatically terminate your rights to use
the Program under this License.  However, parties who have received
copies, or rights to use copies, from you under this General Public
License will not have their licenses terminated so long as such parties
remain in full compliance.
X
@item
By copying, distributing or modifying the Program (or any work based
on the Program) you indicate your acceptance of this license to do so,
and all its terms and conditions.
X
@item
Each time you redistribute the Program (or any work based on the
Program), the recipient automatically receives a license from the original
licensor to copy, distribute or modify the Program subject to these
terms and conditions.  You may not impose any further restrictions on the
recipients' exercise of the rights granted herein.
X
@item
The Free Software Foundation may publish revised and/or new versions
of the General Public License from time to time.  Such new versions will
be similar in spirit to the present version, but may differ in detail to
address new problems or concerns.
X
Each version is given a distinguishing version number.  If the Program
specifies a version number of the license which applies to it and ``any
later version'', you have the option of following the terms and conditions
either of that version or of any later version published by the Free
Software Foundation.  If the Program does not specify a version number of
the license, you may choose any version ever published by the Free Software
Foundation.
X
@item
If you wish to incorporate parts of the Program into other free
programs whose distribution conditions are different, write to the author
to ask for permission.  For software which is copyrighted by the Free
Software Foundation, write to the Free Software Foundation; we sometimes
make exceptions for this.  Our decision will be guided by the two goals
of preserving the free status of all derivatives of our free software and
of promoting the sharing and reuse of software generally.

@section What is Calc?
X
@noindent
@dfn{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:
X
@itemize @bullet
@item
Choice of algebraic or RPN (stack-based) entry of calculations.
X
@item
Arbitrary precision integers and floating-point numbers.
X
@item
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.
X
@item
Mathematical operations such as logarithms and trigonometric functions.
X
@item
Programmer's features (bitwise operations, non-decimal numbers).
X
@item
Financial functions such as future value and internal rate of return.
X
@item
Number theoretical features such as prime factorization and arithmetic
modulo @i{M} for any @i{M}.
X
@item
Algebraic manipulation features, including symbolic calculus.
X
@item
Moving data to and from regular editing buffers.
X
@item
``Embedded mode'' for manipulating Calc formulas and data directly
inside any editing buffer.
X
@item
Graphics using GNUPLOT, a versatile (and free) plotting program.
X
@item
Easy programming using keyboard macros, algebraic formulas,
algebraic rewrite rules, or extended Emacs Lisp.
@end itemize
X
Calc tries to include a little something for everyone; as a result it is
large and might be intimidating to the first-time user.  If you plan to
use Calc only as a traditional desk calculator, all you really need to
read is the ``Getting Started'' chapter of this manual and possibly the
first few sections of the tutorial.  As you become more comfortable with
the program you can learn its additional features.  In terms of efficiency,
scope and depth, Calc cannot replace a powerful tool like Mathematica@c{\trademark}
@asis{ (tm)}.
But Calc has the advantages of convenience, portability, and availability
of the source code.  And, of course, it's free!

Reference.  If so, both volumes will include a copy of the
``getting started'' chapter.

X
At the end of the present chapter is a brief ``demonstration'' which
illustrates the major features of Calc in just a couple of pages.  If
you are in a hurry to use Calc, this will show you everything you need
to know to begin.
X
The tutorial chapter walks you through the various parts of Calc
with lots of hands-on examples and explanations.  If you are new
to Calc and you have some time, try going through at least the
beginning of the tutorial.  The tutorial includes over 50 exercises
with answers.  These exercises give you some guided practice with
Calc, as well as pointing out some interesting and unusual ways
to use Calc's features.
X
The reference section discusses Calc in complete depth.  The reference
can be read from start to finish if you want to learn every aspect
of Calc.  Or, you can look in the table of contents or the Concept
Index to find the parts of the manual that discuss the things you
need to know.
X
You can access this manual on-line at any time within Calc by
pressing the @kbd{h i} key sequence.  Outside of the Calc window,
you can press @kbd{M-# i} to read the manual on-line.  Also, you
can jump directly to the Tutorial by pressing @kbd{h t} or @kbd{M-# t},
or to the Summary by pressing @kbd{h s} or @kbd{M-# s}.  Within Calc,
you can also go to the part of the manual describing any Calc key,
function, or variable using @w{@kbd{h k}}, @kbd{h f}, or @kbd{h v},
respectively.
X
@node Notations Used in This Manual, Using Calc, About This Manual, Getting Started
@section Notations Used in This Manual
X
@noindent
This section describes the various notations that are used
throughout the Calc manual.
X
In keystroke sequences, uppercase letters mean you must hold down
the shift key while typing the letter.  Keys pressed with Control
held down are shown as @kbd{C-x}.  Keys pressed with Meta held down
are shown as @kbd{M-x}.  Other notations are @key{RET} for the
Return key, @key{SPC} for the space bar, @key{TAB} for the Tab key,
@key{DEL} for the Delete key, and @key{LFD} for the Line-Feed key
(@kbd{C-j} if you don't have this key on your keyboard).
X
Sometimes the @key{RET} key is not shown when it is ``obvious''
that you must press @kbd{RET} to proceed.  For example, the @key{RET}
is usually omitted in key sequences like @kbd{M-x calc-keypad @key{RET}}.
X
Commands are generally shown like this:  @kbd{p} (@code{calc-precision})
or @kbd{M-# k} (@code{calc-keypad}).  This means that the command is
normally used by pressing the @kbd{p} key or @kbd{M-# k} key sequence,
but it also has the full-name equivalent shown, e.g., @kbd{M-x calc-precision}.
X
Commands that correspond to functions in algebraic notation
are written:  @kbd{C} (@code{calc-cos}) [@code{cos}].  This means
the @kbd{C} key is equivalent to @kbd{M-x calc-cos}, and that
the corresponding function in an algebraic-style formula would
be @samp{cos(@var{x})}.
X
A few commands don't have key equivalents:  @code{calc-sincos}
[@code{sincos}].@refill

Calc has several user interfaces that are specialized for
different kinds of tasks.  As well as Calc's standard interface,
there are Quick Mode, Keypad Mode, and Embedded Mode.
X
@c [fix-ref Installation]

@node Starting Calc, The Standard Interface, Using Calc, Using Calc
@subsection Starting Calc
X
@noindent
On most systems, you can type @kbd{M-#} to start the Calculator.
The notation @kbd{M-#} is short for @kbd{@key{META}-#}.  On most
keyboards this means holding down the @key{META} (or @key{ALT}) and
@key{SHIFT} keys while typing @kbd{3}.
X
@cindex META key
If you don't have a @key{META} key on your keyboard, you can type
@key{ESC} first, then @kbd{#}, to accomplish the same thing.  If you
don't even have an @key{ESC} key, you can fake it by holding down
@key{CTRL} or @key{CONTROL} while typing a left square bracket
(that's @kbd{C-[} in Emacs notation).@refill
X
@kbd{M-#} is a @dfn{prefix key}; when you press it, Emacs waits for
you to press a second key to complete the command.  In this case,
you will follow @kbd{M-#} with a letter (upper- or lower-case, it
doesn't matter for @kbd{M-#}) that says which Calc interface you
want to use.
X
To get Calc's standard interface, type @kbd{M-# c}.  To get
Keypad Mode, type @kbd{M-# k}.  Type @kbd{M-# ?} to get a brief
list of the available options, and type a second @kbd{?} to get
a complete list.
X
To ease typing, @kbd{M-# M-#} (or @kbd{M-# #} if that's easier)
also works to start Calc.  It starts the same interface (either
@kbd{M-# c} or @w{@kbd{M-# k}}) that you last used, selecting the
@kbd{M-# c} interface by default.  (If your installation has
a special function key set up to act like @kbd{M-#}, hitting that
function key twice is just like hitting @kbd{M-# M-#}.)
X
If @kbd{M-#} doesn't work for you, you can always type explicit
commands like @kbd{M-x calc} (for the standard user interface) or
@w{@kbd{M-x calc-keypad}} (for Keypad Mode).  First type @kbd{M-x}
(that's @key{META} with the letter @kbd{x}), then, at the prompt,
type the full command (like @kbd{calc-keypad}) and press Return.
X
If you type @kbd{M-x calc} and Emacs still doesn't recognize the
command (it will say @samp{[No match]} when you try to press
@key{RET}), then Calc has not been properly installed.
X
The same commands (like @kbd{M-# c} or @kbd{M-# M-#}) that start
the Calculator also turn it off if it is already on.
