Функция string() преобразует свой аргумент к строковому типу. Эта функция обычно не используется явно в преобразованиях, так как в большинстве случаев она вызывается по умолчанию. Преобразование 1 является примером конвертации чисел в строковой тип. Обратите внимание на результат деления на 0.

Преобразование 1

Исходный Surf
<source>

<number>9</number>

<P>9/0 = Infinity</P>
<P>-9/0 = -Infinity</P>
<P>0/0 = NaN</P>
