Whiteboard
Numeric field widget should allow entering formula, instead of just number.
This IMO is much better than calling out a "visual calculator box"... and simpler to program too.
I think it is not hard to make but can be one of those "why I love openerp" factors for end-users.
Example
user entry >> result saved in table
9 >> 9
-9*2 >> -18
4.33333333 >> 4.333
8/3 + 2 >> 4.333 (rounding should work just the same as user would enter say 10 decimals)
(8+2)*2 >> 20
abc >> validation error: not numeric
Basic arithmetic should be ample sufficient. powers and sin() and so on are not needed (though - if using some expression evaluation engine, should not be forcefully excluded).
