当我输入0.0001。输出为0.0001。当我输入0.00001或更多0在1之前。然后我得到1.0e-5或值大于5。
这是我在管理面板上的索引。

index do
    selectable_column
    column :id
    column :transaction_type
    column "Single Coin Worth($)", :single_coin_worth
    
    # actions defaults: true #for all actions like(edit, show and delete)
    actions defaults: false do |coin_setting|
      item "Show", admin_setting_path(coin_setting), class: "member_link"
      item "Edit", edit_admin_setting_path(coin_setting), class: "member_link"
    end
  end

我还想限制输入字段中e表示法。
这是我的fourm管理面板

form do |f| 
    f.semantic_errors *f.object.errors[:base]
    f.inputs do
      f.input :single_coin_worth, {required: true, min: 0, max: 100000}
      f.input :transaction_type, as: :select, collection: ['purchase', 'withdrawl']
      f.actions
    end
  end

我在模型中有这些验证

validates :single_coin_worth, presence: true

validates :single_coin_worth, numericality: {:less_than_or_equal_to => 1}

validates :single_coin_worth, numericality: {:greater_than => 0}

validates :transaction_type, presence: true, inclusion: {in: ['purchase', 'withdrawl']}

我希望输出数字与输入相同。我也想限制所有的东西在输入字段ecept小数点和数字。
