Clover currently always fractions of cents ending in .5 up. A common, and more accurate, method of rounding called Bankers Rounding will round .5 up for odd numbers, and down for even numbers. So 1.5 cents rounds to 2 cents, and 2.5 cents also rounds to 2 cents.

Please allow the tax computation method to be changed to Bankers Rounding. This can be done per account, going forward, and should not affect historical calculations since it's only used to calculate the amount of tax to be paid at the time of sale.

Here is a website explaining how this works: https://rounding.to/understanding-the-bankers-rounding/
