Awile ago I thought there would be hundreds of free calculator programs out there, easy to find a good advanced one. Then I looked… My results were very disappointing.
Today I came across a nice new free calculator released July 2008:
Precise Calculator by Petr Laštovička
You can adjust precision of this calculator (for example to 1000 digits). It knows all usual mathematical functions, statistical functions, prime numbers, PI, matrices, complex numbers, integral and it is programmable (commands if, goto, print, return, …).[/quote:2glijywc]

Free High Precision Complex Calculator
Another new calculator released October 2008.programmable calculator that does a real or complex number calculations with 100 significant figure precision. Many standard functions such as trig, hyperbolic, logarithms, and base conversions are included. Loops are supported. Both expressions and results can be saved to a file.[/quote:2glijywc]

ARIBAS
This one actually dates back to 1997. Latest release is February 2008.ARIBAS is an interactive interpreter for big integer arithmetic and multiprecision floating point arithmetic with a Pascal/Modula like syntax. It has several builtin functions for algorithmic number theory like gcd, Jacobi symbol, Rabin probabilistic prime test, factorization algorithms (Pollard rho, elliptic curve, continued fraction, quadratic sieve), etc.[/quote:2glijywc]
(Awhile ago I thought of integrating ARIBAS with MultiEdit as a replacement for MultiEdit’s somewhat outdated calculator. But that will have to wait for my next lifetime.)

January 14, 2009 at 4:50 pm #8301geofffParticipantIt’s a little oldschool, but I still think that , the emulator for the greatest calculator in history, is a fine option, especially since HP released the HP48 ROMS to the public years ago. Of course, prefer the real deal. After my 48SX from college died a couple of years ago, I grabbed a 48S and 48G from ebay to keep onhand.
Or, if you’re a UNIX lover, install the CygWin32 environment and fire up trusty "bc".
However, for a product that isn’t 20+ years old in the making, there’s a personal favorite of mine: . It’s portable (being a Java app), and is crazy easy to do unit conversions with. Can be run from web interface (embedded Java app), or it can be run from the commandline (which is how I run in from own FreeBSD workstation).
