# OEIS

## About

This a gem to interface the [On-Line Encyclopedia of Integer Sequences](http://oeis.org) 

(OEIS). It allows you to search for a documented sequence using a Ruby Fixnum Array as

input.

## Usage

    > require 'oeis'

    > ls = 3.upto(10).collect { |i| i*i }

    [9, 16, 25, 36, 49, 64, 81, 100] 

    > result = OEIS::search(ls)

    

    > p result.title

    The squares: a(n) = n^2.

    > p result.id

    A000290

    > p result.sequence

    [0, 1, 4, 9, 16, 25, 36, 49, 64, 81, 100 ...

    

## Installation

    git clone git@github.com:prezjordan/oeis.git

    cd oeis

    bundle

    gem build oeis.gemspec

    gem install oeis-X.X.X.gem

    

**OR**

    gem install oeis

    

## Why?

I started working on this gem after my roommate's snoring kept me from sleeping. It is my

first gem, so there's a *very* good chance I did something wrong, or did something 

not-so-right. 

Numbers have always been a passion of mine, so this servers as a simple educational tool.

Generating numbers is fun, seeing various properties of the numbers you just generated is

even cooler.
