I've started to learn python and tried command: print(-2.989 + 2) it gives me result of -0.9889999999999999 same error can be observed with numbers from 4 and below like: print(-2.989 + 4) 1.0110000000000001 print(-2.989 + 3) 0.01100000000000012 print(-2.989 + 1) -1.9889999999999999 Numbers above 4 seam to work fine |

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 |
