Add a bits attribute to np.finfo() (Trac #1288) #1886

Original ticket http://projects.scipy.org/numpy/ticket/1288 on 2009-11-06 by @astrofrog, assigned to unknown.

The number of bits occupied by an integer type can be found from:

In [6]: np.iinfo(np.int16).bits

Out[6]: 16

but this is not currently possible for floats:

In [7]: np.finfo(np.float32).bits

AttributeError Traceback (most recent call

AttributeError: 'finfo' object has no attribute 'bits'

Would it be possible to implement this?
