It will be nice to have this operator, x || y = x*y/(x+y)

If you have installed the include plugin you can define your prefered functions in a file that you include when they are needed.

hi faufnews, I know how to define a function but, I need a operator

Operators are hardcoded in SMath; to have an electrical operators palette I can suggest you to open a request in the Issues Tracker, with a list of operators, the symbols and the corresponding formulas. (The same if you want a plugin with "dressed functions", like those shown here)
If you like my plugins please consider to support the program buying a license; for personal contributions to me: paypal.me/dcprojects

I would like this, too. It's

Mathcad has been used in most of my circuit calculation, by I found it will be useful if I can do it in free SmathStudio so that I can share them to other people who hasn't paid for Mathcad.
There are a lot of Mathcad example on http://www.circuitsage.com/. And you can see this parallel resistance operator has been predefined in all their Mathcad work sheets.
This parallel resistance operator is not to speed up the calculation in computer but to simply the result in low entropy symbolic format for the reading and understanding of human. It is only used for resistor R and impedance Z, because C can be written as Zc=1/sC. This is the format what has been used in all the publication and we don't use C1 || C2.

Thank you for sharing the links, I've found a little bit of documentation.
I can start a new plugin, "Electrical Engineering Library", in the spare time.
I propose the following functions as first entries:
- EEL_Rpar(#) - Equivalent resistance of resistors in parallel (dressed, as your request)
- EEL_Rser(#) - Equivalent resistance of resistors in series (undressed)
- EEL_Cpar(#) - Equivalent capacitance of capacitors in parallel (undressed)
- EEL_Cser(#) - Equivalent capacitance of capacitors in series (undressed, or dressed if you want)
# is for "undefined number of entries"

Ah, good point. For resistors and inductors and impedances, the || signifies them being in parallel. For capacitors, it is used when capacitors are in series, not in parallel, but you can use the same notation since it is the same calculation.
