[OASIS Issue Tracker] Updated: (OFFICE-1469) Public Comment:[office-formula] Domain problems with exponential operator andfunctionPOWER

[ http://tools.oasis-open.org/issues/browse/OFFICE-1469?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Robert Weir  updated OFFICE-1469:
---------------------------------

    Proposal: 
1) Move the statement of the allowed values of 0^0 from the definition of the ^ operator in 5.4.6 to the semantics statement in the definition of POWER() in 5.16.46.

2) We should add the following semantic constraints to POWER():

a) POWER(0,0) is implementation-defined, but shall be one of 0,1, or an Error
b) POWER(0,b), where b < 0, shall return an error.
c) POWER(a,b), where a<=0 and INT(b)!=b, is implementation defined.

The ^ operator is defined in section 5.4.6.  The POWER() is defined in 5.16.46.  The ^ operator is defined in terms of the POWER() function.

I don't think either definition should talk about numeric underflow, overflow, limited precision, complex parameters, or any similar issues which are shared by all functions.  Remember, even the + operator can cause an overflow error.  We should define those concerns once , for all functions and operators.
