JavaScript Basics: | |
1. Напишите функцию, рассчитывающую размер ипотечного аннуитетного платежа. Функция должна принимать размер кредита в долларах, процентную ставку за период и количество периодов. Для расчета платежа воспользуйтесь формулой на странице http://ru.wikipedia.org/wiki/%D0%98%D0%BF%D0%BE%D1%82%D0%B5%D0%BA%D0%B0. | |
2. Создайте метод у всех числовых объектов, который бы выводил значение числа от 0 до 99 в виде слов. Например, число 45 должно выводиться как "сорок пять" (англ. "forty-five"). Для выполнения задания используйте свойство prototype. | |
3. Напишите функцию для создания такой таблицы размером NхM, чтобы каждая ячейка заполнялась случайной буквой английского алфавита и случайным цветом фона (для выполнения задания воспользуйтесь методом random() объекта Math, кроме того, создайте массив в элементами – буквами алфавита). |
