Add More Decimal Places to Percentage

If you need more decimals, like 1.04567

open woocommerce-bulk-discount.php
search round
round( $d[0], 2 ) replace with round( $d[0], 10 )
and replace number 2 with any number you need (eg. 10)
there is several places for this replacement.

This should be included in plugin. Two decimal places are not enough.

eg. I need price range:
1-4: 2540
5-9: 2450
and discount is 3.54331%
