I had a new brainstorming session and would like to expand on some issues/
Specifications:
What__________| How
is____________| should it be
entered_______| interpreted
==============|=============
SIMPLE NUMBER:
* Number (e.g. 4) => as plain number
* negative number (-3) => as negative plain number
* '+' + 'Number' => as STRING !!!
-- this is currently interpreted as a number, too, but in categorical data you
may have often categories of, e.g. '+4' which is different from '4' (think of
grades in histology and so on);
NOTE: when we have only one number [regardless of the +/-/(or nothing) in front
of that number], the formula does *NOT bring* any *additional benefit*, so I do
NOT believe that a formula is needed in these situations!!!)
NUMBER FOLLOWED BY OPERATOR:
* 'plain number'+'any operator' => string
* '+' + 'plain number' + 'any operator' => formula
* '-' + 'plain number' + 'any operator' => string (formula?)
* ('+' or '-') + '-' + 'plain number' + 'any op' => formula; strip first +/-
-- advanced: IF "'any operator'..." does evaluate to *ERROR*, consider string
instead of formula
STRING:
* any string => string
* ('+' OR '-') + STRING
-- IF string evaluates to valid function => formula
-- IF NOT => just a string
