The Steps: cont.

Step 6: Now we need to deal with the afterPrice, since it's separate from the rest of the figure. Let's check the length:

   Comment: ===================
   Comment: format cents
   Set Variable: "/:afterPriceLen" = MBLength(/:afterPrice)

Step 7: If afterPrice's length = nothing, that means that we have a number like 10, so we want to add a 00 to it:

   If (/:afterPriceLen = "" or /:afterPriceLen = 0)
   	Set Variable: "/:afterPrice" = "00"

Step 8: If afterPrice is 1 digit, then we know we need to tack a zero onto it:

   Else If (/:afterPriceLen = 1)
   	Set Variable: "/:afterPrice" = /:afterPrice & "0"

Step 9: Now it gets really fun - what happens if our sum is longer than 2, such as 10.5356? We'll have to chop the afterPrice off at 2, being sure to round up if it needs to be rounded:

   	Comment: round up if the decimal warrants it
   	If (MBSubstring ( /:afterPrice, 3, 1 ) > 4)
   		Set Variable: "/:afterPrice" = MBSubstring ( /:afterPrice, 1, 2 )
   		Set Variable: "/:afterPrice" = /:afterPrice + 1
   		Set Variable: "/:afterPrice" = MBSubstring ( /:afterPrice, 1, 2 )
   	End If
   End If

Step 10: Finally! We put together all of our pieces and add a nice "$" and a ".":

   Set Variable: "/:displayPrice" = "$" & /:beforePrice    & "."& /:afterPrice

In this particular example, we send users on to the result screen, and then allow them to input a new price and check it. This is really for demonstration purposes, unless you're looking to create a really, really boring "format the price!" game :)

» Description: Hmm... what to say about this one? It's reminiscent of the closing notes of the opening music from the Three Stooges done in a church organ style with a closing cymbal crash. I'll give this one away gratis, but feel free to check out my free loops and potential upcoming license-mandated ones over in the respective part of Flashkit.
