# SDAC

The **S**oftware **D**efined **A**utomatic **C**alculator, is a research project that aims to implement a programmable calculator with its own [LISP](https://en.wikipedia.org/wiki/Lisp_(programming_language)) dialect.

### Types

**Expressions** (exp): Things to be evaluated.

**Values** (val): Things that are evaluated.

### Keywords

| Keyword | Symbol |    Description   |

|:-------:|:------:|:----------------:|

|   add   |    +   |     Addition     |

|   mul   |    *   |  Multiplication  |

|   sub   |    -   |    Subtraction   |

|   div   |    /   |     Division     |

|   mod   |    %   |      Modulus     |

|   and   |    &   |        AND       |

|   ior   |   \|   |   Inclusive OR   |

|   xor   |    ^   |   Exclusive OR   |

|   eqa   |    =   |     Equality     |

|   neq   |    !   |   Non Equality   |

|   min   |    <   |      Minimum     |

|   max   |    >   |      Maximum     |

|   eif   |    ?   | Evaluate if true |

### Example (The answer to everything)

**Input**

```lisp

(exp mul (val . 21) (exp add (val . 3) (val . -1)))

```

**Output**

```

+ 3 -1

* 21 2

: 42

```

For which ':' is the complete evaluation of the program.

Meaning that the answer to life, the universe, and everything is 42.
