Hi All,

This is with reference to issue  #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?

Not sure if it makes sense here, but elsewhere (I think it was polyval) we let object arrays through unchanged.
