Hello H2X,
Did you get any response from Swissmicros (if you asked one or both) ?
Thomas
Yes!

### Re: Little Problem with Complex Mathematics on Calculators

My intuition demands not that infinity be a number or have limits, but it insists that there is structure. It would be surprised if there is a finite "number" of such structures. Allow me to repeat myself: https://en.m.wikipedia.org/wiki/Aleph_number There are infinitely many different infinite car...

### Re: Little Problem with Complex Mathematics on Calculators

While there is an infinite number of integer values, it seems logical that the also infinite number of rational numbers is larger, and real numbers larger still. It isn't logical. There are the same number of rational numbers as there are integers, this we proved by Cantor. There are more real numb...

### Re: Little Problem with Complex Mathematics on Calculators

Thomas, I agree and disagree. Is the set of even numbers as big as the set of odd numbers? And is not the set of integers the union of these? Which set is bigger? My intuition is screaming. What I see when I try to envision these infinities is different sets of numbers growing at different rates, th...

### Re: Little Problem with Complex Mathematics on Calculators

I am not an expert either, but clearly there are kinds of infinities which cannot be easily compared. While there is an infinite number of integer values, it seems logical that the also infinite number of rational numbers is larger, and real numbers larger still. It seems intuitive that there shoul...

### Re: Little Problem with Complex Mathematics on Calculators

Anyway I'm not an expert in these matters so I would like to ear from more competent people. I am not an expert either, but clearly there are kinds of infinities which cannot be easily compared. While there is an infinite number of integer values, it seems logical that the also infinite number of r...

### Re: Little Problem with Complex Mathematics on Calculators

We all know that SQRT( -∞ ) = i ∞ . The calculator returns 0. + i ∞ which is perfectly equivalent. Probably not competent either, but I know that infinity is tricky... For example you can also say that -i + i ∞ is perfectly equivalent to i ∞ . But (-i + i ∞ )*(-i + i ∞ ) = -1 - ∞ +2 ∞ which is unde...

But (0 + i )^2 = 0 + (-∞) + 2 i 0 = -∞ + 2 i 0 .
Aren't you assuming that 0 times ∞ is defined yourself? If 0 times ∞ is undefined, 2 i 0 ∞ is not defined either?
