[Numpy-discussion] Behavior from a change in dtype?

Hello all,
I ran into a problem with some of my older code (since figured out the
user error). However, in trying to give a simple example that
replicates the problem I was having, I ran into this.
In [19]: a = np.array((1.))
In [20]: a
Out[20]: array(1.0)
# the dtype is 'float64'
In [21]: a.dtype='<i8'
In [22]: a
Out[22]: array(4607182418800017408)
I've seen some recent threads about handling changes in types, but I
didn't follow closely, so forgive me if I'm missing something that is
known. In general, is it just a bad idea to touch the dtype like
this?
Best,
Skipper
