1.1 What is Calc?
=================
“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.
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. Calc does not have
the scope and depth of a fully-functional symbolic math package, but
Calc has the advantages of convenience, portability, and freedom.
