How do you round an float(input(float_input_variable)

Question

Hello,

I am currently working on a simple calculator that Asks a user for the cost and quantity of an item that they bought from a store. My problem is that when the user inputs a quantity of: 5 and a price of $2.22 the program returns a total cost of 10.1000000001. I tried using the rounding function but to no avail. Can you tell me how to prevent the program from doing that?

Thank you,

Andrew

Print(‘Hello! Let me calculate the cost of your purchase’)
print()
cost_iphone=float(input(‘How much was your iphone? ‘))
print()
num_iphones=float(input(‘How many iPhones? ‘))
Print()
total_cost= cost_iphone * num_iphones
print()
print(‘Your total cost is’, ‘$’, total_cost ‘)
