I've barely begun to look into it. Of course, it does mean getting
Emacs, and learning enough Emacs and creating enough Emacs macros to
get up and running.
Other than the learning curve, it's free. It certainly has the
capabilities your client needs. And Emacs is an incredibly handy tool
to have and know.
>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.
