[Numpy-discussion] linalg.norm probems

Hi All,

This is with reference to issue  #5626
<https://github.com/numpy/numpy/issues/5626>. Currently linalg.norm
converts the input like so `x = asarray(x)`. This can produce integer
arrays, which in turn may create problems of overflow, or the failure of
the abs functions for minimum values of signed integer types. I propose to
convert the input to a minimum precision of float32. However, this will be
a change in behavior. I'd guess that that might not be much of a problem,
as otherwise it is likely that this problem would have been reported
earlier.

Thoughts?

Chuck
