Tax rouding up instead of down.

[pmonosolo]

Preconditions (*)

1. Magento 2.4.3 CE
2. Product with price $38.48
3. Taxes: Canadian GST (5%) and PST(7%) taxes applied to order
4. GST tax: 38.48 * 0.5 = 1.924 ~ 1.93
5. PST tax $38.48 * 0.7 = 2.6936 ~ 2.7

Both PST and GST are being rounded up even though they should not be. I believe it should be rounding up only at 0.5 not at 0.4.

This creates a misalignment when orders get synced into Quickbooks.

Steps to reproduce (*)

1. Create a product with price $38.48

2. Create Tax Rate for GST

3. Create Tax Rate for PST

4. Create Tax Rule for for GST

5. Create Tax Rule for PST

6. Put product with price 38.48 into cart and go to checkout

7. Check out with address from Canada, British Columbia

Expected result (*)

1. Order Total should be $43.09

Actual result (*)

1. Order Total Shows $43.10 (which actually is incorrect even by the broken rouding up system - 38.48 + 2.70 + 1.93 = 43.11)

Hi @pmonosolo,

Thank you for reporting the issue.

I have tried this issue on the fresh installation (Magento 2.4-dev/2.4.3-P1) but I am not able to reproduce it with given steps

Kindly recheck the issue on Magento 2.4-develop branch and elaborate the steps if the issue is still reproducible.
Thank you.
