Example
Python Compiler
import math
num = 1000001
arr = [0]*50
i = -1
total = 0
while(num != 0):
i += 1
arr[i] = num % 10
num = math.floor(num / 10)
for j in range(i, -1, -1):
total += arr[j] * math.pow(2, j)
print("Decimal number of 1000001 (binary) is %d" % math.floor(total))
Output
Decimal number of 1000001 (binary) is 65
Converter any Given Binary Number to Decimal Number
In the following example, we will convert any given binary number to a decimal number.
Example
Python Compiler
import math
num = int(input("Enter a Binary Number: "));
copyNum = num
arr = [0]*50
i = -1
total = 0
while(copyNum != 0):
i += 1
arr[i] = copyNum % 10
copyNum = math.floor(copyNum / 10)
for j in range(i, -1, -1):
total += arr[j] * math.pow(2, j)
print("Decimal number of %d (binary) is %d" % (num, math.floor(total)))
Output
Enter a Binary Number: 10
Decimal number of 10 (binary) is 2
