формула - выражение, составленное из чисел, переменной x, операций + - * / и функций: sin, cos, tg ,ctg (остальные в проекте).
примеры:
=sin(x)*x
=x/2
=cos(sin(cos(x)+1)+1)+1
=1/x
в случае ошибки вычисления(не найдена функция, деление на 0) программа не выводит никаких сообщений, а либо вылетает, либо считает результат недопустимой операции нулевым.
== v 0.3 ==== 7.06.08
добавлено много чего из интерфейса.
функции: log, exp, sqrt.
== v 0.4 ===== 9.06.08
улучшен ввод имени файла, обработка ошибок, фиксы утечек памяти.
