Калькуляторы (Calculators)

Усовершенствованный калькулятор (TeleCalc)

Описание:

Этот сценарий работает как обычный калькулятор, но главное в нем – это возможность ведения статистики. Если нажать "more options" (дополнительные функции), то появляются новые кнопки, с помощью которых можно ввести ваше число. После нажатия кнопки "Add" (Добавить) можно ввести другие числа. Теперь можно сразу узнать минимальное, максимальное, среднее значения и даже открыть окно с текстом всей подготовленной статистики, если нажать кнопку "Sta".

Текст JavaScript-сценария: Calculators: TeleCalc
Просто выделите текст внутри формы, расположенной внизу, и скопируйте его (нажмите Ctrl-C или Apple-C) в новый текстовый файл программы-редактора (например, NotePad или Simple Text). После этого сохраните его (Ctrl-S или Command-S). Теперь вы можете использовать исходный текст сценария для решения своих задач!!!
