# RCCP - Rust Calculator for Cool People

## Overview

RCCP is a simple command-line calculator written in Rust as an alternative to more conventional GUI calculators. It supports basic arithmetic calculation, and respects the order of operation (BIDMAS/BODMAS/PEMDAS).

## Features

- Basic arithmetic operations: addition (

), subtraction (`+`

), multiplication (`-`

), and division (`*`

).`/` - Exponents: use the

symbol to perform exponentiation (e.g.,`^`

equals 8).`2``^``3` - Factorial: use the

symbol to calculate the factorial of a number (e.g.,`!`

equals 120).`5``!` - Sqare root: use

to calculete the sqare root of a number (e.g.,`sqrt`

)`sqrt``(``9``)` - Trigonometry: use

,`sin`

, and`cos`

in your equations (e.g.,`tan`

)`sin``(``16``)` - Logorithm: use

to calculate the logorithmic of a number (e.g.,`log`

)`log``(``100``)` - Order of operations: operations are performed in the correct order according to BODMAS/BIDMAS/PEDMAS rules.
- Parentheses: parentheses can be used to change the order of operations.
- Simple Command Line Interface

## Installation

To install RCCP, you can use the rust package manager: cargo.

`$`` curl https://sh.rustup.rs`` -`sSf `|` `sh`
`$`` cargo install rccp`
`$`` rccp`

Or you can build it from source, using the github repository.

`$`` git clone https://github.com/d3vboi/rccp.git`
`$`` cd rccp`
`$`` curl https://sh.rustup.rs`` -`sSf `|` `sh`
`$`` cargo run`` -`q

Keep in mind, if you use this method you will need to be in the RCCP directory to be able to run the cargo command.

## Usage

To use RCCP, simply run the program, then enter an expression at the prompt:

`$`` rccp`
`>` `2` `+`` 3 ``*` 4
`14`
`>` exit

As we can see in this example, RCCP correctly performs the multiplication before the addition, resulting in the *14* instead of *20*.
You do not need to add spaces in between characters.

is also a valid expression.`>` `2``+``3``*``4`
