Kelvin
A small library for handling temperatures.
It's as precise as a 64 bit Float.
Installation
Add this to your application's shard.yml
:
dependencies:
kelvin:
github: tijn/kelvin
Usage
require "kelvin"
temperature = Kelvin::Temperature.celcius(22.3)
puts temperature
# => "22.3 °C" : String
# or if you're in the US, it will output: "72.1 °F" : String
# It follows the LOCALE settings on your system.
puts temperature.to_kelvin
# => 295.45
It can also parse text:
require "kelvin"
temperature = Kelvin::Temperature.parse("22.3 °C")
puts temperature
# => "22.3 °C" : String
and you can use it to compare temperatures on different scales.
temperature_in_paris = Kelvin::Temperature.parse("22.3 °C")
temperature_in_boston = Kelvin::Temperature.parse("70.1 °F")
city = (temperature_in_paris > temperature_in_boston) ? "Paris" : "Boston"
puts "#{city} is warmer today"
