Adding more decimal after comma in price in plugin (only plugin not woocommerce)

Hi

This plugin has a big problem with the rounding of prices that give the wrong totals, you need to add at least 4 decimals in the price calculation plugin, if you add from woocommerce then they also appear in the shopping cart and other parts of the site, you need the possibility to add decimals to the prices only for the plugin without having to add them from the woocommerce settings which are then modified also in the cart and in the totals. All discount calculations are wrong in this way, it would be necessary for the plugin to have its own decimal setting in order to calculate prices correctly.
