# simple-arithmetic

## c++ version

A tiny & high-performance calculation class without other dependencies.  

You can use it simply like:

```cpp

string s = "(1+1+1+1) ^ tan(((2+2)+(3-2)) * 0.5)";

ArithmeticExpression expression(s);

if(expression)

{

    printf("%s = %g\n", s.c_str(), expression.value());

}

```

or with variable `x` and `y`:

```cpp

string s = "cos(x^2) + sin(y)^2";

ArithmeticExpression expression(s);

if(expression)

{

    expression.setX(0.8);

    expression.setY(1.5);

    printf("%s = %g\n", s.c_str(), expression.value());

}

```

### How to use

Just add `arithmetic.cpp` & `arithmetic.h` to your project.
