Provide C++ examples of floating point calculations when the result is +0 and -0?

Question

C++ / C#

The teacher at the university gave the task "to present in C ++ examples of floating point calculations when the result is +0 and -0". After a few hours of watching video lectures, I still didn’t understand what was happening. Is there anyone fumbling around here?

Answer 1

Divide in a cycle a positive number by 10 and a negative number by 10. Sooner or later, you will get +0 and -0.
