# Calculator (2016)

Calculator is a simple command-line calculator. I have programmed the calculator to better understand how parsers work. The program is written in `C`

and without any third-party libraries.

It can handle the following operations:

- Pi Pi number
- e Euler’s number
- sqrt() Square root
- cos() Cosine
- sin() Sine
- tan() Tangent
- lg() Decimal logarithm
- ln() Natural logarithm
- () Brackets
- || Absolute value
- ! Factorial
- Unary minus
- ^ Exponent
- % Modulus divide
- *, / Multiply, Divide
- +, - Add, Subtract

The source code and build instructions can be found on GitHub.
