Subject: [PATCH] GH-13122: Skip factorial() float tests on Python 3.10
|
|
|
|
special.factorial() argument should be an array of integers.
|
|
On Python 3.10, math.factorial() reject float.
|
|
On Python 3.9, a DeprecationWarning is emitted.
|
|
A numpy array casts all integers to float if the array contains a
|
|
single NaN.
