input: Write a function to convert a temperature from Celsius to Fahrenheit. The function should take a single parameter representing the temperature in Celsius and return the equivalent temperature in Fahrenheit rounded to two decimal places.
  assert celsiusToFahrenheit(0)==32.0
  assert celsiusToFahrenheit(100)==212.0
  assert celsiusToFahrenheit(25)==77.0
  assert celsiusToFahrenheit(-40)==-40.0
  assert celsiusToFahrenheit(37)==98.6
output: def celsiusToFahrenheit(celsius):
      return round((celsius * 9/5) + 32, 2)
