# Feature request – rounding precision

 * Hi
 * I have many small products which means that when a coupon is applied the rounding
   is not accurate enough (using GBP with 2 decimal places being displayed). This
   means I need `wc_get_rounding_precision()` to return 6 rather than 4.
 * I can’t see a way of doing this as WC_ROUNDING_PRECISION is a constant 4, so 
   would it be possible to add a filter to `wc_get_rounding_precision()` please?
 * E.g.
 *     ```
       function wc_get_rounding_precision() {
       	$precision = wc_get_price_decimals() + 2;
       	if ( absint( WC_ROUNDING_PRECISION ) > $precision ) {
       		$precision = absint( WC_ROUNDING_PRECISION );
       	}
       	apply_filters( 'woocommerce_rounding_precision', $precision );
       	return $precision;
       }
       ```
   
 * Many thanks! A great plugin.
    Mike

 * Just set the WC_ROUNDING_PRECISION constant in your wp-config file.
