Fibonacho

Fibonacho is a gem for finding the largest integer value from the Fibonacci Sequence smaller than the given integer because you never know when that will come in handy...

Not affiliated with nachos, but you're encouraged to eat some while using this gem.

Installation

gem install fibonacho

Then in your project

require 'rubygems'
require 'fibonacho'

Or add to your Gemfile

gem 'fibonacho'

Usage

This gem adds the methods closest_fibonacci methods to Ruby's Fixnum class. Eg.

156.closest_fibonacci
=> 144

99.closest_fibonacci
=> 89

Rationale

Given the requirement that closest_fibonacci be a method callable on an integer, this gem will add it's method to Ruby's Fixnum class. Version 0.1 of this gem uses a simple loop to construct a series of Fibonacci numbers that breaks when it reaches a number that is equal to or greater than the number we're comparing it to. We then return the last number in the loop.

A more production suitable gem would probably employ a technique more memory efficient than this.

Notes

Written with Ruby 1.9.2 (p290).
