[New-bugs-announce] [issue16460] Strange results for floor division ("//") with non-integer divisors

[Tom Pohl]

New submission from Tom Pohl:

According to the documentation of the floor division (http://docs.python.org/2/reference/expressions.html#binary-arithmetic-operations), x//y should be equal to math.floor(x/y).

However, the result of 1//0.1 is 9.0 (tested on 2.6, 2.7, 3.2).

It might be related to the internal representation of floating-point numbers, but for this example I would expect it to come up with the correct values.

Cheers,
Tom
