Isn't simply using integers enough?

1 = 10 / 10
-0.2 = 2 / 10
-0.2 = 2 / 10
-0.2 = 2 / 10
-0.2 = 2 / 10
-0.2 = 2 / 10
= 0 / 10 = 0
and now you have no problem.
Just store an integer and how many times it has been multiplied by 10
compared to the real value.
Then when doing an operation make sure that number is the same for both.
