Rails 3視圖 - 向上舍入

Question

我有一個Rails視圖來顯示PERIOD和GENERAL LEDGER的網格，我想顯示累計總數。但是，在下面的情況下，我的@cumulative_total在「TOTAL」列中四捨五入到最接近的美元，因此即使在general_ledger列中正確顯示，也不會顯示美分。任何想法我做錯了什麼？

<% @cumulative_total = 0 %> 
<div id="gl_crosstab"> 
    <table> 
    <tr> 
     <th>Period</th> 
     <% @general_ledgers.each do |g| %> 
     <th><%= g.general_ledger_number %></th> 
     <% end %> 
     <th>Total</th> 
     <th>% Expended</th> 
    </tr> 
    <% @expected_billings.group_by(&:period_id).each do |eb| %> 
     <tr> 
     <td><%= eb[1].first.period.pe_number %></td> 
     <% eb[1].each do|p| %> 
      <td><%= number_to_currency(p.expected_amount) %></td> 
     <% end %> 
     <td> 
      <% @cumulative_total = @cumulative_total + eb[1].inject(0){|sum,billing| sum+billing.expected_amount.to_i} %> 
      <%= number_to_currency(@cumulative_total) %> </td> 
     <td><%= number_to_currency((@cumulative_total/@sla.project_total)*100) %> % </td> 
     </tr> 
    <% end %> 
    <tr> 
     <td><b>Total Budget</td> 
     <% @total_expected_billings.each do |teb| %> 
     <td><b><%= number_to_currency(teb[1].inject(0){|sum,billing| sum+billing.expected_amount.to_i}) %></td> 
     <% end %> 
     <td><b><%= number_to_currency(@expected_billings.inject(0){|sum,billing| sum+billing.expected_amount.to_i}) %> </td> 
     <td><b><%= number_to_currency((@expected_billings.inject(0){|sum,billing| sum+billing.expected_amount.to_i}/@sla.project_total)*100) %> % </b></td> 
    </tr> 
    </table> 
</div> 

Answer 1

我認爲這是因爲你開票金額轉換成 '整數'，同時顯示：

@expected_billings.inject(0){|sum,billing| sum+billing.expected_amount.to_i 

如果更改

billing.expected_amount.to_i 

到

billing.expected_amount.to_f 

它應該工作。
