input: Write a function to convert a given temperature in Celsius to Fahrenheit. The function should return the temperature rounded to 2 decimal places.
  assert celsiusToFahrenheit(37.0) == 98.6
  assert celsiusToFahrenheit(-40.0) == -40.0
  assert celsiusToFahrenheit(0.0) == 32.0
  assert celsiusToFahrenheit(100.0) == 212.0
output: def celsiusToFahrenheit(celsius):
      return round((celsius * 9/5) + 32, 2)
