Binary

Simple Ruby gem to convert integers into binaries and binaries into integers

Installation

Add this line to your application's Gemfile:

gem 'binary'

And then execute:

$ bundle

Or install it yourself as:

$ gem install binary

Simply require the gem in your code:

require 'binary'

Then to get the binary representation of a number, you just need to call Binary.binary and pass the number to it, something like follows:

Binary.binary 2018

Or

2018.to_b

Output: "11111100010".

Also you can pass an array of integers to the method to get an array of their binary values.

Binary.binary([[7,9,11])

Or

[7,9,11].to_b

Output: ["111", "1001", "1011"].

You can also convert binaries into integers by calling method number as follows:

Binary.number "11111100010"

Or

"11111100010".to_num

Output: 2018.

Binary.number(["111", "1001", "1011"])

Or

["111", "1001", "1011"].to_num

Output: [7,9,11].

Other methods available:

# number of bits in a number's binary
Binary.bits 1000

Output: 10.

# number of ones in a number's binary
Binary.ones 1000

Output: 6.

# number of zeros in a number's binary
Binary.zeros 1000

Output: 4.

# get array of binaries of all prime numbers between 2 and the given number
Binary.prime 25

Output: ["10", "11", "101", "111", "1011", "1101", "10001", "10011", "10111"].
