Because your height attribute is a floating point number and doing calculations on floating point numbers in the binary system  is imprecise.

If you want further information why this is the case, here are two good starting points:

I tried "Summerize Nearby". And I wanted him to summery atributes within the range I entered. I had i.e. 2 Features in that range and the atribute "hight" in bothes Features were 1 . The Result suppode to be 2. But but in the new atrubte field it says 1,99989.  Can someone explain me , why it is like that?
