I've set up a custom item field DISC_PCT of PERCENT type with the default value calculated using the following formula (store value unchecked):

ROUND(({pricelevel1}-{pricelevel5})/{pricelevel1},3)

This custom field is called by item template through javascript to display the % discount on any item that is onsale.  Silly issue but I can't get the percentage to simply display in integer format.  If I use:

ROUND(({pricelevel1}-{pricelevel5})/{pricelevel1},3) - it displays "46.9%"
ROUND(({pricelevel1}-{pricelevel5})/{pricelevel1},2) - displays "47.0%"
ROUND(({pricelevel1}-{pricelevel5})/{pricelevel1},1) - displays "0.0%"

I simply want to drop all decimal places and round or truncate to the whole integer for display purposes.  I tried TRUNC but it didn't work either.
