Maxima-5.23.2



Barton:

I'm breathing easy...

The sum() method is now producing an error message for the 0^0 
condition, which it should. When I originally reported I was having 
problems (I was using Maxima-5.20.1), the sum() method was producing '0' 
for that condition, which was giving me incorrect results. I should have 
left out the part about the sum() method in my original posting for "Re: 
[Maxima] Maxima-5.23.2" because that was partially fixed some time ago. 
I just grabbed the input I had used in a message concerning "Re: 
[Maxima] Maxima 5.22.0" to indicate that things were still the same for 
Maxima 5.23.2. I should have been more discerning and only presented the 
part that was incorrect.

I wasn't advocating a 0^0 --> 1 solution. Even my TI calculator doesn't 
recognize that as valid. The input 0^i gives 0 as output before Maxima 
knows anything about 'i' whereas my TI calculator produces an error 
message telling me that 'i' is undefined. Once 'i' is assumed to be 
'>=0' then 0^i in Maxima it again produces 0 for output as I think it 
should NOT, but rather it should indicate an error for 0^0.

These "little" errors catch me napping periodically by producing 
incorrect results that I have to chase down to discover if the problem 
is in my math (more often than I want to admit) or Maxima's results.
