** my _form.html.erb**

<tr>
  <th><%= f.label :click_your_deposit_amount %></th>    
</tr>
<tr>
  <td> 
    <%= f.check_box :depamt, {:multiple => "true"}, 500 %>500

    <%= f.check_box :depamt, {:multiple => "true"}, 1000 %>1000

    <%= f.check_box :depamt, {:multiple => "true"}, 2000 %>2000

    <%= f.check_box :depamt, {:multiple => "true"}, 3000 %>3000

  </td>
</tr>    
<tr>
  <td>
    <span id="span"></span>
    <div>Total Deposit Amount: <span id="amt"> </span></div>
  </td>
</tr>

<script>
  $('input:checkbox').change(function(){ 
    var total = 0;
    $('input:checkbox:checked').each(function(){
      total+=parseInt($(this).val());
      $('#amt').html(total)
      }); 
    });
</script>

Probably the easiest thing to do is create a "depamt" serialized column for Fds (typically a text column is used in the database). ActiveRecord will automatically persist and fetch Array values for you. See the documentation here for examples of configuring your model.

The problem is that you are trying to call the .to_f method on an Array. You could call that method on items in the array, but not the array itself: 

new_array = my_array.map(&:to_f)

This should convert all the items to floats and set this as a new array.
