Why is it type double and not Int?

Hey guys, I was doing this code challenge and, I just don't know what to do and I hope one of you guys can help me out with my problem, I just don't understand why would temperature be in Double and not in Int, I know, the divide and multiply numbers are Integers, but I was just trying something. So I hope someone can help me out! Thanks.

functions.swift 
// Enter your code below
func temperatureInFahrenheit(temperature: Double, multiply: Double, divide: Double, plus: Double) -> Double {
    let temperatureInFahrenheit = (temperature * multiply / divide + plus)
    return temperatureInFahrenheit
}

Hi Justus,

Your function is not quite right. You want the function to take a single input named temperature. The calculation to convert the temperature value to Fahrenheit takes place within the function itself.

func temperatureInFahrenheit(temperature: Double) -> Double {
    return (temperature * 9)/5 + 32
}
