Tax Report Shows Wrong Total

[miqrogroove]

I'm trying out OpenCart v1.5.6.2.

There seems to be a problem with the Taxes report. It is counting fractions of a cent in the total, even though taxes will always be charged and collected in whole cents.

To test, I created two orders that would have $0.11 tax.

The Tax Report shows a total of $0.23. :(

I'm not sure where to begin with the PHP code, but I did notice this in the database:

SELECT order_id, text, value FROM oc_order_total WHERE code='tax'

order_id | text | value
2 | $0.11 | 0.1114
3 | $0.11 | 0.1147

It looks like the text column values are correct.
