Subject Re: Calc behavior: result of 0 ^ 0
Date Tue, 12 Feb 2013 19:11:33 GMT

I don't understand,

I saw a bug (erroneous result returned by a function) and I fixed
it respecting the standards, thereby enhancing interperability
with the market leader.

I am aware that Rob has a different point of view here but so
far neither him nor Stephen Hawking has explained how the change
would be incorrect and no example where someone has been affected
by this change has been provided.

Has the patch been vetoed, and if so on what basis?
