So this is "expected" behavior?
In [1]: np.logaddexp2(-1.5849625007211563, -53.584962500721154) Out[1]: -1.5849625007211561
In [2]: np.logaddexp2(-0.5849625007211563, -53.584962500721154) Out[2]: nan
Is any able to reproduce this? I don't get 'nan' in either 1.4.0 or 2.0.0.dev8313 (32 bit Mac OSX). In an earlier email T J reported using 1.5.0.dev8106.
Having the config.h as well as the compilation options would be most useful, to determine which functions are coming from the system, and which one are the numpy ones, cheers, David
