Incorrect results from Subtraction

This is the logic. A simple subtraction of 7.95 from 11.95, which should equal 4. Instead, Backendless gives me 3.999999999999999


If I change the logic from subtraction to addition I get 19.90 as expected.

It is not Backendless, that’s how JS works in a browser:

Thanks, @mark-piller. I didn’t see that one coming.
