      Um conjunto de sobrecargas ou um modelo de função para todas as combinações de argumentos do tipo aritmética não cobertos por 1-3). Se algum argumento tem tipo integral, ele é convertido para double. Se algum argumento é long double, então o Promoted tipo de retorno é também long double, caso contrário, o tipo de retorno é sempre double.
      Original:
