Hello,

I'm always wondering why binary_repr doesn't allow arrays as input values. I always have to use a work around like:

import numpy as np

def binary_repr(arr, width=None): binary_list = map((lambda foo: np.binary_repr(foo, width)), arr.flatten()) str_len_max = len(np.binary_repr(arr.max(), width=width)) str_len_min = len(np.binary_repr(arr.min(), width=width)) if str_len_max > str_len_min: str_len = str_len_max else: str_len = str_len_min binary_array = np.fromiter(binary_list, dtype='|S'+str(str_len)) return binary_array.reshape(arr.shape)

Is there a reason why arrays are not supported or is there another function that does support arrays?

Not sure if there was/is a reason, but imho it would be nice to have support for arrays. Also in base_repr. Could you file a ticket in trac?

Cheers, Ralf
