Consider the phedd link - there are a lot of sites with command line bc formulas, for example fft solutions. bc originally was meant to do extended precision floating point from extensive scripts, as well as one-off fp math operations. Don't sell it short.

If you want portability and you do not want to have to verify/install perl's MATH:: for every UNIX installation, bc is the correct approach, IMO.

NAME
isympy - interactive shell for SymPy SYNOPSIS
isympy [-c | --console] isympy [ {-h | --help} | {-v | --version} ] DESCRIPTION
isympy is a Python shell for SymPy. It is just a normal python shell (ipython shell if you have the ipython package installed) that exe- cutes the following commands so that you don't have to: >>> from __future__ import division >>> from sympy import * >>> x, y, z = symbols("xyz") >>> k, m, n = symbols("kmn", integer=True) So starting isympy is equivalent to starting python (or ipython) and executing the above commands by hand. It is intended for easy and quick experimentation with SymPy. For more complicated programs, it is recommended to write a script and import things explicitly (using the "from sympy import sin, log, Symbol, ..." idiom). OPTIONS
-c shell, --console=shell Use the specified shell (python or ipython) as console backend instead of the default one (ipython if present or python otherwise). Example: isympy -c python FILES
${HOME}/.sympy-history Saves the history of commands when using the python shell as backend. BUGS
The upstreams BTS can be found at <http://code.google.com/p/sympy/issues/list> Please report all bugs that you find in there, this will help improve the overall quality of SymPy. SEE ALSO
