why is this python code giving me problems?

This is having the user input a decimal number and the code has to round it up to the 2nd decimal place. This code is giving me problems, please fix it.
num3 = int(input("Please input a decimal number:")
num3 = int(round(num3, 2))
print ("your decimal rounded to the 2nd decimal place is:", x)
