HexValues

Gem Version Code Climate Build Status Coverage Status

Transform your float to hexadecimals and viceversa!

Installation

Add this line to your application's Gemfile:

gem 'hex_values'

And then execute:

$ bundle

Or install it yourself as:

$ gem install hex_values

Usage

require the gem:

require 'hex_values'

And then transform any float to a hexadecimal:

234.25.to_hex
# => "EA.4"

Or transform any hexadecimal to the corresponding float:

"EA.4".to_float
# => 234.25

Hexadecimal

To be more precise, when you transoform a Float (or a Fixnum) to an hexadecimal, you get a Hexadecimal object. This object is a representation of the Hexadecimal value, and you can operate on this object:

hexa = 234.25.to_hex
result = hexa + 234.25
result.to_s
# => "1D4.8"

also you can operate over a Float (or a Fixnum) using an Hexadecimal value.

hexa = 234.25.to_hex
result = 234.25 + hexa # I know, this is obvious...but is better to explain that works.
result.to_s
# => "1D4.8"

So far, the operations availables are:

  • plus (+)
  • minus (-)
  • multiply (*)
  • division (/)
  • Power (**)

From float to Hex

The "to_hex" method allows a precision parameter to set the maximum number of decimals to calculate (default 14).

Bear in mind that the larger the number, the larger the amount of time used to get the number:

1875.37.to_hex(50)
# => 753.5EB851EB851EB851EB851EB851EB851EB851EB851EB851EB85
