numpy.binary_repr(num, width=None)
[source]
Return the binary representation of the input number as a string.
For negative numbers, if width is not given, a minus sign is added to the front. If width is given, the two’s complement of the number is returned, with respect to that width.
In a two’scomplement system negative numbers are represented by the two’s complement of the absolute value. This is the most common method of representing signed integers on computers [1]. A Nbit two’scomplement system can represent every integer in the range to .
Parameters: 


Returns:

binary_repr
is equivalent to using base_repr
with base 2, but about 25x faster.

The two’s complement is returned when the input number is negative and width is specified:
>>> np.binary_repr(3, width=3) '101' >>> np.binary_repr(3, width=5) '11101'
