Простой калькулятор
===================

[](#простой-калькулятор)

Очень простой, тривиальный калькулятор. Быстрый, без внешних зависимостей. Поддерживаются только четыре арифметических действия (без приоритетов!) и вычисление процентов. Можно использовать для вычисления простых наценок, например, для начисления налогов.

Примеры
-------

[](#примеры)

```
Calculator::calc("5+5"); // 10

Calculator::calc("10-2"); // 8

Calculator::calc("5*2"); // 10

Calculator::calc("5+5*2"); // 20. Внимание! приоритеты не поддерживаются!

Calculator::calc("5%", 200); // 10

Calculator::calc("10+5%", 200); // 20

Calculator::calc("10+5%+20%"); // 60
```
