Python code to check whether given hexadecimal number is equal to the provided decimal number

 

Python code for converting hexadecimal to decimal numbers And Check whether given hex number is equal to

provided decimal number:

 

# Make a dictionary of Hexadecimal to decimal conversion table

HexToDecimalConvTable = {'0': 0, '1': 1, '2': 2, '3': 3, '4': 4, '5': 5, '6': 6, '7': 7, '8': 8, '9': 9,

'A': 10 , 'B': 11, 'C': 12, 'D': 13, 'E': 14, 'F': 15}

 

# Enter some hexadecimal number (strip remmove space and upper convert into Capital Latter)

hexadecimalNumber = input("Enter the hexadecimal number: ").strip().upper()

 

#Enter the provided decimal number

decimalNumber=int(input("Enter provided decimal number: "))

decimal = 0

 

#computing max power value

power = len(hexadecimalNumber) -1

 

for digit in hexadecimalNumber:

    decimal += HexToDecimalConvTable[digit]*16**power

    power -= 1

   

print(decimal)

 

# decimal is calculated decimal number

if(decimalNumber == decimal):

    print("Given Hexadecimal is equal to decimal number")

else:

    print("Hexadecimal number is not match with decimal")

 

 

#Input is FF

#Output is 255

The standard mathematical way to convert hexadecimal to decimal is to multiply each digit of hexadecimal number with corresponding power of 16 and sum it.

Like: decimal += HexToDecimalConvTable[digit]*16**power
