A frequent question we receive is how to use the shell calculator to compute a recursive function. Here is an example for factorial:

http://www.shellcalc.com/#reverse=false%23%23factorial%20=%20function%28n%29%20{%20return%20n%20%3E%201%20?%20n%20*%20factorial%28n%20-%201%29%20:%201%20}%23%23factorial%285%29

http://www.shellcalc.com is a powerful scientific shell calculator. It can evaluate a wide range of mathematical expressions and supports variable assignment. Computations are structured as a worksheet that you can save and share. Very convenient!

If you are used to starting a Python interpreter for miscellaneous computation needs, then shell calc is a perfect replacement.
