Hi Everyone:

   Please help as i need to write some rounding function in C#. i
Wrote one but does not give me correct result. Can some one please
correct me

C# Codes

#########################################################################
dblVal = 1234567.89

private int ThreeSifFig(double dblVal)
   {
       int lngvalue;
       int threesigfig;
       int lngvaluelen;

       lngvalue = (int)(Math.Abs(dblVal));
       lngvaluelen = lngvalue.ToString().Length;
       if ((lngvaluelen <= 1))
       {
           threesigfig = 0;
       }
       else if ((lngvaluelen <= 3))
       {
           threesigfig = (lngvalue / 10) * 10;
       }
       else
       {
           threesigfig = (lngvalue / 10 ^ (lngvaluelen - 3) * 10) ^
(lngvaluelen - 3);
       }
       if ((dblVal < 0))
       {
           threesigfig = (threesigfig * -1);
       }

       return threesigfig;

   }

Return Result is 123500 but the expected result is 1230000

VB.NET code which return correct result
Protected Sub Page_Load(ByVal sender As Object, ByVal e As
System.EventArgs) Handles Me.Load

       Dim sval As Double = 1234567.89
       Dim lngvalue, lngvaluelen As Long
       Dim threesigfig As Long
       lngvalue = Int(Math.Abs(Val(sval)))
       lngvaluelen = Len(CStr(lngvalue))
       If lngvaluelen <= 1 Then
           threesigfig = 0
       ElseIf lngvaluelen <= 3 Then
           threesigfig = Int(lngvalue / 10) * 10
       Else
           threesigfig = Int(lngvalue / 10 ^ (lngvaluelen - 3)) * 10
^ (lngvaluelen - 3)
       End If
       If sval < 0 Then
           threesigfig = threesigfig * -1
       End If
   End Sub

Result is 1230000 [Correct]

Thanks in advance.
