Multiplication of two binary number in python by R4R Team

Binary number

-It is a number which expressed in the base-2 numeral system,
-Binary numbers are 0 or 1.

Multiplication of two binary number -

Example-

b1=101 // 5 in decimal
b2=101 // 5 in decimal

then multiplication of b1 and b2 is 11001 // 25 in decimal

program -

print("Enter first binary number")
n=input()
print("Enter second binary number")
m=input()

s=bin(int(n,2)*int(m,2))
print("Multiplication of two binary number is - "+s)

output -

Enter first binary number
101
Enter second binary number
101
Multiplication of two binary number is - 0b11001

Enter first binary number
1010
Enter second binary number
101
Multiplication of two binary number is - 0b110010

-In this program, firstly we take two input,
- int(n,2) derive the decimal equivalent so we find the decimal of both the number then multiple
- then using the bin() function we convert the decimal number into binary again. and this is the required ans.
