[issue22544] Inconsistent cmath.log behaviour

[Per Brodtkorb]

Per Brodtkorb added the comment:

This is not only a problem for division. It also applies to multiplication as exemplified here:

>>> complex(0,inf)+1  # expect 1 + infj
Out[16]: (1+infj)

>>> (complex(0,inf)+1)*1  # expect 1 + infj
Out[17]: (nan+infj)

>>> complex(inf, 0) + 1j  # expect inf + 1j
Out[18]: (inf+1j)

>>> (complex(inf, 0)+1j)*1  # expect inf + 1j
Out[19]: (inf, nanj)
