Write two functions that convert temperatures from Fahrenheit to Celsius, and vice versa:
convertToCelsius(32) // fahrenheit to celsius, should return 0
convertToFahrenheit(0) // celsius to fahrenheit, should return 32
Because we are human, we want the result temperature to be rounded to one decimal place: i.e., convertToCelsius(100) should return 37.8 and not 37.77777777777778.
This exercise asks you to create more than one function so the module.exports section of the spec file looks a little different this time. Nothing to worry about, we're just packaging both functions into a single object to be exported.
