New submission from Michał Jan Warecki:
This should speak for itself:
>>> 3*4.35
13.049
>>>
The error is reproducible, and applies to all decimal numbers ending with
\.[0-9]5, and \.[0-4] as well as \.[6-9], when multiplied by 3. Examples:
>>> 3*4.1
12.299
>>> 3*4.4
13.201
>>> 3*4.6
13.799
>>> 3*4.8
14.399
>>> 3*4.9
14.701
>>> 4*3.1
12.4
>>> 4*4.1
16.4
>>> 3*4.1
12.299
>>> 6*4.1
24.5999998
>>> 6*4.4
26.402
>>>
