Dumb question time...
How do I scale/round in a .bsh script? I need to mangle some reports to
handle VAT/GST and I need to work with values significant to 2 decimal
places. This has got to be obvious, but not to me in my bleary eyed state...
For example, I want calculate an item's GST to 2 decimal places I will
display the GST on an invoice and sum a series of these "itemGSTs" to
calculate a tax subtotal, and naturally, I want the displayed values
and the subtotal not to exhibit any discrepancies.
Currently I'm using things like
<#assign itemGST=(invoiceItem.quantity?double *
invoiceItem.amount?double * 0.10)>
to calculate, and
<@ofbizCurrency amount=itemGST isoCode=invoice.currencyUomId?if_exists/>
to display the values. Obviously, the latter is applying some
scaling/rounding rules, and I want to apply the same rules to my running
totals to make sure things add up.
Assistance appreciated...
Cheers, Iain
