Currency rounding
The requirement is to round cash sale invoice values to the nearest multiple of the smallest currency denomination. Rounding is required where a currency's low denomination coins have been withdrawn, but the currency’s subdivisions remain the same. If payment is tendered using non-cash methods, no rounding is required. Various rounding interval standards apply.
India specific
The amount of tax, interest, penalty, fine, or any other sum payable, and the amount of refund or any other sum due, must be rounded off to the nearest rupee. If the value in paise is more than 50 paise, it is rounded up to the nearest rupee and if the value in paise is less than 50 paise, it is rounded down to the nearest rupee
