**Project Name:-** Binary Calculator (Infinite Precision Calculator)

### DESCRIPTION :-  

  * This is the **Command line Arbitrary precision calculator** which is implemented using _C Programming language_.

  * It tries to implement some functionalities from unix based command **'bc'**.

  ---

  * Operations performed on countably infinite length numbers are as follows:-

    * Addition

    * Substraction

    * Multiplication

    * Division

    * Modulus  

    * SquareRoot

    * Trignometric Functions like Sine, Cosine, Tangent, input angle is considered in radian units

    * Length of the Number

    * exponential i.e e(x)

    * Factorial of a Number (try 3 digit numbers only) . _Try 1000! on Google calculator it says infinite :)_

  ---

  * All expressions are evaluated according to their **_precedence_**.

  * _paranthesis_ '()' can be used which is having higher precedence.  

  * All the operations performed are stored in  _history.txt_ file, for future reference

  

  

  ---

  

### Execution Instruction :-  

 * Clone the repository on your machine. 

 * Open **Terminal** and _change directory_ to the project directory.  

 * Type command ' **make** ' which will compile the required files and generate _executable file_.   (Linux/Mac recommended)

 * Then type the command ' **./project** '. 

 * Run `./project -h` to get a list of all operations that it can perform

 * `./project `  will take input from the file and output it on the terminal, example: `./project test.txt`

 * An enter key on empty line exits the program

  ---

  ### DataStructures used :-

**A Doubly Linked List of struct node with Head and tail pointer**

  

**For tokenizing the Input String, I had used Finite State Machine**
