> -7 divided by 2 is -3, not -4
Integer division in Python is floor division, and it's self-consistent with the
implementation of the modulo operation such that the following identity is
satisfied: (a % n) == a - n * (a // n). For example:
(-7 % 2) == -7 - 2 * (-7 // 2)
1 == -7 - 2 * (-4)
== -7 + 8
This behavior is consistent with mathematical analysis languages such as
MATLAB, Mathematica, Mathcad, and R. It's also consistent with Ruby, Perl, and
Tcl. However, it's different from C, C++, C#, Java, PHP and many other
languages. See the following Wikipedia article:

Please do not change the status and resolution of this issue again. This is not
a bug.
