Specifically I was referring to standard float representation which permits signed zeros. However, other comments provide some interesting examples also.
Yes, mathematically it's the same, but in physics there's a guy named Heisenberg who denies that 0.99999... really gets to 1.
There is always this difference, for a mathematician infinite is not a problem, but for a physicist it is, plus a very big one.
What do you mean? In two's complement, there is only one zero.

Who use ones complement?
I assume no one at this point
I think 1's complement only existed to facilitate 2's complement. Otherwise its stupid
1- 0,99999....
Floating point numbers are not possible in two's complement, besides that, what is your point? 0,99999999... is probably the same as 1.

True, it sounds like that might be a problem if we consider that physics has to be between math and computer science.
