Время изготовления : в идеале можно за 2 часа, чтобы нарисовать все картинки. Раскидать их по своим местам, и быстро написать ужасный и неразборчивый не ООП код, чтоб этот состав костылей кое-как ездил.
На самом деле пришлось потратить 10-12 часов, на всякие перерывы, исправления и поиск ошибок, бесконечно приходящие идеи , типа сделать проверки на отрицательные числа и четные показатели степени, или сделать блокировщик ввода двух точек или двух минусов под корень, ведь у числа максимум одна точка отделяющая десятичную дробь от целого.
А самое неприятное оказалось внезапно , то что
ява скрипт относиться к языкам неумеющим производить точные вычисления. Например он умножает 0.03*0.03 = 0.0009
0000000045
