[Numpy-discussion] Why doesn't array(a, dtype=single, copy=0) downcast a double array.

[Charles R H. <cha...@gm...>]

It seems to me that since the behaviour when copy=0 is to make a copy only
if necessary, it should find it necessary and make the downcast. After all,
array(a, dtype=single, copy=1) does just that without complaint. Some common
code in linalg could be replaced if array and asarray would do that
operation.
