把长的数字用逗号隔开显示

March 25,2004

Code Title: Proper Number
Description: If you have a long number to display, then why not make it split the number up correctly with
a comma?

For example, the number 12345678 looks odd, right? Ok, let's apply the Comma() function to that number and
display it like this automatically: 12,345,678 -much cleaner!

By the way, this script supports numbers as long as 15 characters (numbers), so if you have a longer
number than that, we may need to work together to advance this script a bit, but this snippet will work
just fine for your average numbers. Thanx to Dave Cantrell for this advice!
Copy and paste this snippet as-is into your editor:

000000000000000000000000000000000000000000000000000000000000000
<%
Function Comma(str)
If Not(IsNumeric(str)) Or str = 0 Then
  Result = 0
ElseIf Len(Fix(str)) < 4 Then
  Result = str
Else
  Pos = Instr(1,str,".")
  If Pos > 0 Then
Dec = Mid(str,Pos)
  End if
  Res = StrReverse(Fix(str))
  LoopCount = 1
  While LoopCount <= Len(Res)
  TempResult = TempResult + Mid(Res,LoopCount,3)
  LoopCount = LoopCount + 3
  If LoopCount <= Len(Res) Then
TempResult = TempResult + ","
  End If
  Wend
  Result = StrReverse(TempResult) + Dec
End If
Comma = Result
End Function
