FireFox Removes My Trailing '0'

Question

I have a web page which in some fields displays values stored on a server but if any other these end with '0' or '.00' it removes them so £1.10 would be £1.1 and £10.00 would be £10.

In my code I have them as Decimals so I would have expected it to show the entire values. If I use Chrome or IE it works fine for me, my issue is just with FF.

In my view

<%
    Decimal sum = 0;
    Decimal totalTrancheValues = 0;
    var isCappeddrawdown = false;

    foreach (var tranche in benefitDetails.Tranches)
    {
        //Adds all remaining incomes for 'Capped drawdown' and give a total for them all
        if (tranche.FundType == "Capped drawdown")
        {
            sum = sum + Convert.ToDecimal(tranche.GrossIncomeRemainingThisPensionYear == null ? 0 : tranche.GrossIncomeRemainingThisPensionYear);
            isCappeddrawdown = true;
        }

        //Adds totals for all tranches
        totalTrancheValues = totalTrancheValues + Convert.ToDecimal(tranche.Value == null ? 0 : tranche.Value);
    }
%>

<div class="form-group">
     <label class="col-sm-offset-1 col-sm-4 control-label">SIPP cash balance</label>
     <div class="col-sm-4">
          <input id="SIPPCashBalance_Textbox" name"SIPPCashBalance_Textbox" value=<%: Math.Round(client.Sipp.Cash, 2) %> disabled />
     </div>
</div>
<% if (isCappeddrawdown)
{%>
     <div class="form-group">
          <label class="col-sm-offset-1 col-sm-4 control-label">Remaining income</label>
          <div class="col-sm-4">
               <input id="RemainingIncome_Textbox" name="RemainingIncome_Textbox" value=<%: sum %> disabled />
          </div>
     </div>
<%} %>

I tried wrapping convert.todecimal around my 'sum' but it just will not work

When I use F12 it says my value is value="30.00" but on my webpage it displays only as 30

I have tried using it as a string and have tried string.Format("{0:C}", sum) and sum.toString() but my field just will not display the '.00'

Jeroen comment is correct.

Switch <%: sum %> to <%: sum.ToString("£ 0.00") %> or even better: <%: string.Format("{0:C}", sum) %>, which works with locale, making your string format localized.

Edit: The "C" refers to a Currency format, which inherits from the CultureInfo. That makes it easy to localize your application. Most .Net classes override the .ToString() method to supply many different formats (specially numbers).
