Subject: Computations on properties
Date: Wed, 9 Oct 2013 12:19:52 +0000 (UTC)	[thread overview]
Message-ID: <loom.20131009T141208-743@post.gmane.org> (raw)

Hi,
  I'm seeking how to do something like that

Let the following text inserted in an org-mode file

* Mean Calculation
 :PROPERTIES:
 :VAL1: 5
 :VAL2: 10
 :COEF: 10
 :END:

I would like to append the result of a computation 
like RES=(VAL1*COEF+VAL2)/(COEF+1) 

Something like 
* Mean Calculation
...
  :END:

Mean Calculation=RES (where RES is the value of the result)

I think to do this with a python script but is there a more org-mode/emacs
method to do it?

Thanks
Thierry 

PS: I don't want to use org spreadsheet
