Mark Dickinson  added the comment:

Thanks for the report. This isn't a Python bug, but a common issue when working 
with floating-point numbers.

I recommend taking a look at this section of the tutorial for more information: 
https://docs.python.org/3.8/tutorial/floatingpoint.html

[issue41269] Wrong subtraction calculations

[Ivan]

New submission from Ivan :

I've started to learn python and tried command:
print(-2.989 + 2)
it gives me result of -0.9889
same error can be observed with numbers from 4 and below like:
print(-2.989 + 4)
1.0111

print(-2.989 + 3)
0.01112

print(-2.989 + 1)
-1.9889

Numbers above 4 seam to work fine
