Because of business logic I need to round all product prices to the nearest thousand.
If i have a price of $18600 i need to change the price to $19000. If i have $18400 i need to change it to $18000.
I've played with
getDisplayValue() methods from
Magento_Framework/Pricing/Render/Amount.php but this does not change the price in all the store.
What file(s) should i modify to affect the behavior in all the store?
