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 In [3]: np.log2(np.exp2(-0.5849625007211563) + np.exp2(-53.584962500721154)) Out[3]: -0.58496250072115608 Shouldn't the result at least behave nicely and just return the larger value? _______________________________________________ NumPy-Discussion mailing list NumPy-Discussion@scipy.org http://mail.scipy.org/mailman/listinfo/numpy-discussion
