numpy.base_repr(number, base=2, padding=0) function is used to return a string representation of a number in the given base system.
For example, decimal number 10 is represented as 1010 in binary whereas it is represented as 12 in octal.
Syntax : numpy.base_repr(number, base=2, padding=0)
Parameters :
number : Input number. Only an integer decimal number can be used as input.
base : [int, optional] Convert number to the base number system. The valid range is 2-36, the default value is 2.
padding : [int, optional] To add number of zeroes on the left. Default is 0.Return : String representation of the input number in base system.
Code #1 : Working
# Python program explaining # base_repr() function import numpy as geek in_num = 10 print ("Input number : ", in_num) out_num = geek.base_repr(in_num, base = 2, padding = 0) print ("binary representation of 10 : ", out_num) |
Output :
Input number : 10 binary representation of 10 : 1010
Code #2 :
# Python program explaining # base_repr() function import numpy as geek in_arr = [5, -8, 21 ] print ("Input array : ", in_arr) print() # binary representation of first array # element without using padding parameter out_num = geek.base_repr(in_arr[0], base = 2) print("binary representation of 5") print ("Without using padding parameter : ", out_num) # binary representation of first array # element using padding parameter out_num = geek.base_repr(in_arr[0], base = 2, padding = 3) print ("Using padding parameter: ", out_num) print() # octal representation of 2nd array # element without using width parameter out_num = geek.base_repr(in_arr[1], base = 8, padding = 0) print("octal representation of -8") print ("Without using padding parameter : ", out_num) # octal representation of 2nd array # element using padding parameter out_num = geek.base_repr(in_arr[1], base = 8, padding = 4) print ("Using padding parameter : ", out_num) print() # hexa-decimal representation of 3rd array # element without using padding parameter out_num = geek.base_repr(in_arr[2], base = 16, padding = 0) print("hexa-decimal representation of 21") print ("Without using padding parameter : ", out_num) # hexa-decimal representation of 3rd array # element using padding parameter out_num = geek.base_repr(in_arr[2], base = 16, padding = 3) print ("Using padding parameter : ", out_num) |
Output :
Input array : [5, -8, 21] binary representation of 5 Without using padding parameter : 101 Using padding parameter: 000101 octal representation of -8 Without using padding parameter : -10 Using padding parameter : -000010 hexa-decimal representation of 21 Without using padding parameter : 15 Using padding parameter : 00015
