How to Decode Reputation Levels in Ruby

The reputation for an account is expressed in a long numeric string (like 50453770138701). Here's how to see this value as a reputation level like the steemit.com expresses it (like 67.3260426184728).

As always, we use Radiator with bundler. You can get bundler with this command:

$ gem install bundler

I've tested it on various versions of ruby. The oldest one I got it to work was:

ruby 2.0.0p645 (2015-04-13 revision 50299) [x86_64-darwin14.4.0]

First, make a project folder:

$ mkdir radiator
$ cd radiator

Create a file named Gemfile containing:

source 'https://rubygems.org'
gem 'radiator', github: 'inertia186/radiator'

Then run the command:

$ bundle install

Create a file named rep.rb containing:

require 'rubygems'
require 'bundler/setup'

Bundler.require

puts "Usage: ruby #{__FILE__} <accounts>" and return if ARGV.empty?

api = Radiator::Api.new(url: 'https://node.steem.ws:443')

response = api.get_accounts(ARGV)
accounts = response.result

accounts.each do |account|
  name = account.name
  raw = account.reputation.to_i
  level = Math.log10(raw.abs)
  level = [level - 9, 0].max
  level = (level * 9) + 25

  puts "#{name}, level: #{level}, raw: #{raw}"
end

Then run it:

$ ruby rep.rb abit alexgr bacchist bitcoiner cheftony fubar-bdhr gavvet instructor2121 klye konti liberosist lovejoy nonlinearone patrice pharesim picokernel proctologic proglobyte proglobyte-m1 royaltiffany samupaha steemychicken1 teamsteem tingaling vi1son voteinterestpool zentat

The expected output will be something like this:

abit, level: 65.73535164480853, raw: 33585373526603
