Hi All, The time for NumPy 1.12.0 approaches and I like to have a final decision on the treatment of integers to negative integer powers with the `**` operator. The two alternatives looked to be
*Raise an error for arrays and numpy scalars, including 1 and -1 to negative powers.* *Pluses* - Backward compatible - Allows common powers to be integer, e.g., arange(3)**2 - Consistent with inplace operators - Fixes current wrong behavior. - Preserves type *Minuses* - Integer overflow - Computational inconvenience - Inconsistent with Python integers *Always return a float * *Pluses* - Computational convenience *Minuses* - Loss of type - Possible backward incompatibilities - Not applicable to inplace operators Thoughts? Chuck
