mathmatical expressions evaluation

[Tonino]

thanks all for the info - and yes - speed is not really an issue and no
- it is not an implementation of a complete financial system - but
rather a small subset of a investment portfolio management system
developed by "another company" ...

What I am trying to achieve is to parse a formula(s) and generate a
result ...

I will look into the pyparsing suggested and maybe even leave out
numarrays for now - as it seems a bit overkill ...

The formula are a bit complex and maybe even difficult to write out
Thanks all - I will post my progress ;)
