I'm having a strange issue on Magento Grand Total, using Magento CE 188.8.131.52.
The problem comes when I add the product and put a promo code, that created a change on 0.01€. Changing the precision to 4 or the rounding to 4 sometimes solves the issue but creates issues with payment gateways.
The cart page shows the following info:
Subtotal Excl Tax - 81.29
Subtotal Incl Tax - 99.99
Discount - 25.00
Tax - 14.02
Grand Total - 74.98
The grand total should be 74.99€ (99.99€ from the product - 25.00€ from the discount).
I've tried everything to solve this. Make the math by hand and by certified billing software always return 74.99..
Please help me
