Swift Basics: Operators Extra Credit Challenge

I was wondering if someone could help me. I'm trying to create a formular where you can change any given fahrenheit into celsius. I'm stuck because I am receiving an error every time.

Here is my code:

let degreesInFahrenheit = 70

let degreesInCelseus = (degreesInFahrenheit - 32) * 0.5556

Hi Riley,

I believe it is a type mismatch, one being an int and the other being a double.

Declare them both as type Double and this should resolve it for you, see code below.

let degreesInFahrenheit: Double = 70

let degreesInCelseus: Double = (degreesInFahrenheit - 32) * 0.5556

Thank you Lee!

Thanks for giving me a good answer; it worked! If your following this question, could you please tell me if I have done this the best way possible? Or is there an even better way to do this?

Hi Riley,

I think the answer is about right in terms of efficiency, but someone with a bit more experience than me may be able to give you a better solution.

Cheers
