Hello,

Given the following example:

...

...

float32 foo = np.append(foo, 1)

import numpy as np foo = np.array([], dtype=np.float32) print a.dtype print foo.dtype

...

...

float64

Is this the correct behaviour? I realise that numpy.append() returns a new copy of foo but is it the correct behaviour that the original datatype is not persisted? If so, should this not be noted in the documentation?

Forgive me if I have missed something.

Best wishes
