Subject: Re: [office-formula] Creating the test suite

Makes me wonder if we want to formally adopt IEEE 754 floating point conventions for things like1/0 == +Infinity, but 0/0==NaN, etc.,  at least in the processing model.  Implementations could collapse this all into a single Error string for the user interface if they desired.
