… interface. Code: Added NPY_HALF to switch (descr->type_num) in _buffer_format_string. Added 'e' keys to the _pep3118_native_map and _pep3118_standard_map. Tests: Added entries to the generic round-trip tests. Added specialized half-float test that round-trips example values from the wikipedia page. http://en.wikipedia.org/wiki/Half_precision_floating-point_format http://mail.scipy.org/pipermail/numpy-discussion/2011-March/055795.html
