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?
Thanks,
Markus
