/**

 * What a return is worth when Finance settles it as B2C after NIC refused it for a cancelled or

 * invalid buyer GSTIN: every returned line at its value net of GST, in whole rupees.

 * <p>

 * Standard accounting rounding - each line's net value is rounded HALF_UP to the rupee, and the

 * refund is the sum of those lines, so the line table and the total always agree. The gross is

 * rounded the same way, and the GST retained is simply gross minus refund. The same object feeds

 * the Finance popup, both notification mails and the server-side check of the amount Finance types

 * in, so the three can never disagree.
