numpy.binary_repr(number, width=None) function is used to represent binary form 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’s-complement 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.
Syntax : numpy.binary_repr(number, width=None)
number : Input number. Only an integer decimal number can be used as input.
width : [int, optional] The length of the returned string if number is positive, or the length of the two’s complement if number is negative, provided that width is at least a sufficient number of bits for number to be represented in the designated form.
If the width value is insufficient, it will be ignored, and number will be returned in binary (number > 0) or two’s complement (number < 0) form with its width equal to the minimum number of bits needed to represent the number in the designated form.
Return : binary string representation of the input number.
Code #1 : Working
Input number : 10 binary representation of 10 : 1010
Code #2 :
Input array : [5, -8] Binary representation of 5 Without using width parameter : 101 Using width parameter: 00101 Binary representation of -8 Without using width parameter : -1000 Using width parameter : 11000
