如何将浮点数作为rake任务参数传递？

Question

如何在rake任务中将float number作为参数传递

desc "example rake"
task :to_store_number, [:number1, :number2] do |t, args|
  a = "#{args[:number1].to_f}" * "#{args[:number2].to_f}"
  puts a
end

出现错误“TypeError：没有将String隐式转换为整数”

Answer 1

传递像args [：number]这样的参数而不是＆＃34;＃{args [：number]}＆＃34;修好了

desc "example rake"
task :to_store_number, [:number1, :number2] do |t, args|
  a = args[:number1].to_f * args[:number2].to_f
  puts a
end
