I suggest adding the appropriate conversions into the Microsoft formats input/
output converter and implementing the mathematically correct precedence rule in 
OpenOffice.Org starting from the next major version.

To add further weight to the mathematical correct interpretation:
 - all scientifically advanced programs DO interpret -4^2 = -16
 - including mathematical and statistical software, e.g:
   R, Octave, Mathematica (did not test it personally, but I am confident
   that the person whom I asked, did actually test it), ...

Adding parenthesis (as does gnumeric) is necessary for some other reason, too:
 - files may get imported into different software that:
   -- DO interpret it mathematically correct
   -- BUT do NOT implement all ODF-engine (and every quirk)
  [e.g. a simple ODF-parser/importer]
 - ODF and implementations might change in the future and handle
   such expressions correctly
   -- this will break all backwards-compatibility and
   -- make old spreadsheets rather unusable

To be safe for future changes, removing all mathematical ambiguity when saving
these expressions is the better approach.

Another weirdness of the current implementation is described in issue 92515:
   -(5+3)^2 is interpreted as  + 64  instead of -64
  [tested in OOo-dev m28]
If it wasn't tragic, it would be rather grotesque. In the latter case it can't
be even argued that the number (-8) is meant, because we have -(an
expression). Also, this breaks completely the mathematical commutativity, like:
x - b^n != - b^n + x

Hope this will foster adopting sound mathematical rules in interpreting such
expressions.

In Google, Have yous tried to type -4^2 ?
It resuts -(4^2) = -16.

Confirmed. Input of =-x^y probably should be changed to read =(-x)^y

Not all OpenOffice users are also Excel users (or users of other spreadsheets).
Many of them have used calculators for which the rule is the conventional (and
more common across software) mathematical one: -x^y is -(x^y). So, when the user
types (or copy-pastes) such a formula, OpenOffice should rather interpret it as
-(x^y); there could possibly be a configuration option to support both
interpretations. To avoid any ambiguity, OpenOffice should output explicit
parentheses in both cases.

Concerning file formats, just use the specifications when reading or writing
spreadsheet files. When writing files, adding explicit parentheses could also be
safer, in particular wrt 3rd-party applications that could easily interpret
formulas in the wrong way.

Another remark : properly dealed with by gnumeric : when you type -A1^2 within
gnumeric, the cell receives indeed -(A1^2) with parentheses added. It's the
right solution.

And, of course : the defect remains within OOo 2.4.
Please correct this, it's a pity !
