numpy.binary_repr () in Python

NumPy | Python Methods and Functions

For negative numbers, if no width is specified, a minus sign is added in front. If a width is specified, a two-padded number is returned relative to that width. 
In double`s complement, negative numbers are represented by the double`s complement of an absolute value. This is the most common method of representing signed integers on computers.

Syntax: numpy.binary_repr (number, width = None)

Parameters:
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 & gt; 0) or two`s complement (number & lt; 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: Job

# Python program explaining
# binary_repr () function

 < / code> 

import numpy as geek

in_num = 10

  

print ( "Input number:" , in_num)

 

out_num = geek.binary_repr (in_num) 

print ( "binary representation of 10:" , out_num) 

Output:

 Input number: 10 binary representation of 10:1010 

Code # 2:

# Python program explaining
# binary_repr () function

import numpy as geek

 

in_arr = [ 5 , - 8 ]

 

print ( "Input array:" , in_arr) 

 
# binary representation of the first array
# element without using a width parameter

out_num = geek.binary_repr (in_arr [ 0 ])

print ( "Binary representation of 5" )

print ( "Without using width parameter: " , out_num) 

  
# binary representation of the first array
# element using the width

out_num = geek.binary_repr (in_arr [ 0 ], width = 5 )

print ( "Using w idth parameter: " , out_num) 

  

print ( "Binary representation of -8" )

  
# binary representation of the second array
# element without using width parameter

out_num = geek.binary_repr (in_arr [ 1 ])

print ( "Without using width parameter:" , out_num) 

 
# binary second array representation
# element using th width parameter

out_num = geek. binary_repr (in_arr [ 1 ], width = 5 )

print ( " Using width parameter: " , out_num) 

Output:

 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
