Or am I missing something here? The reason it is not, is because it is not binary compatible with Python's integer. The numpy bool_ is always only 8-bits while the Python integer is 32-bits or 64-bits.
This could be changed I suspect, but then it would break the relationship between scalars and their array counterparts and I'm sure we would not want to bump up all bool arrays to 32 or 64-bits. -Travis _______________________________________________ Numpy-discussion mailing list Numpy-discussion@scipy.org http://projects.scipy.org/mailman/listinfo/numpy-discussion
