Tutorial page "Lifting State Up" demo can give incorrect boiling verdict

Because the Boiling verdict uses the temperature in celsius , if the user puts in fahrenheit 211.9999 this will incorrectly report that it will boil. This is because the conversion to celsius is limited to 3 digits and gets rounded up to 100.

A fix for this is to change BoilingVerdict to accept scale and temperature and the code to do a slightly different check for each:

function BoilingVerdict(props) {
  if (props.scale === 'c' ? props.temperature >= 100 : props.temperature >= 212) {
    return <p>The water would boil.</p>;
  }
  return <p>The water would not boil.</p>;
}

        <BoilingVerdict
          scale={this.state.scale}
          temperature={this.state.temperature} 
          />

I know that I could do a fork and pull request but this is about as far as my interest in this subject goes so anyone else is free to fix this admittedly tiny issue.

Commencez par la page du tutoriel « Lifting State Up » et localisez le composant BoilingVerdict ainsi que son utilisation. Vérifiez le résultat pour des valeurs Fahrenheit juste en dessous de 212, puis mettez à jour le composant et confirmez que 211.9999 n’indique pas l’ébullition, tandis que les valeurs seuil continuent de l’indiquer.
