[Numpy-discussion] Difference in astype() for scalars and arrays?

[Lorenz Hüdepohl]

Hi All,

I'm fiddling with some endianness / binary representation issue and stumbled 
upon this puzzling behavior of astype(): It does not seem to work as 
expected - for me at least ;) - when given a scalar:

 import numpy as np
 np.array(42).astype(i4).dtype
dtype('i4')
 np.array(42, dtype=i4).astype('i4').dtype
dtype('int32')
 
 np.array([42]).astype(i4).dtype
dtype('i4')
 np.array([42], dtype=i4).astype('i4').dtype
dtype('i4')


Shouldn't I always get dtype('i4')?

Regards,
Lorenz

PS:
 np.version.version
'1.4.0.dev7417'
