Quick-entry command line number multiplier (because of some quantitative self efforts I'm doing: http://bit.ly/1MXqjTc)

multiply.rb

#! /usr/bin/ruby

puts "Space-delimit numbers to multiply"
string = gets.chomp

until string.length == 0
  numbers = string.split(/\s+/).map(&:to_f)
  result = numbers.reduce(1.0) {|p, e| p * e}
  puts "Input: #{numbers.inspect}", "Result: ", result, "Another? (return nothing to quit)"
  string = gets.chomp
end
puts "Have a #{%w(great wonderful choodesno unbelievable fantastic worthwhile productive enlightened).sample} day!"
