hi
I have a store Woocommerce and I use the plugin Woocommerce Custom Product Addons
https://wordpress.org/plugins/woo-custom-product-addons/
Where I select product options and link them together with custom pricing and formulas
The problem and the question is that after selecting these options, the total price appears to be an incorrect number, for example 20.01 This is normal due to custom pricing I just want the total on the product page to be rounded to the nearest whole number. Like 20.00
I talked to the plugin developer and gave me a file + image and in fact I have no experience how to fix it

Tell me that this file is brief on the site, and after modifying it, it will be shortened
thank you
