Invoice - Penny Difference with Tax

Hello,

Thoughts on below issue! thanks in advance for your input.

We are observing a Penny difference with Invoice when we compared 'Online Invoice' to 'Printed Invoice'. This difference came up only when we have Tax Summary is turned on (we set to option 3 = Summarize taxes by authority). When we dont turn on this option, then both 'Online Invoice' and 'Printed Invoice' matches. Below are our observations in one of scenario.

Online Invoice -

Order Total. . . 58.52
Taxable Amount 58.52
@ Tax Rate13.000 % 7.62
INVOICE TOTAL 66.14

Printed Invoice -

Invoice Subtotal Before Tax: $58.52
HST: $7.61
Total Amount CAD#: $66.14

In reality, tax on 'Printed Invoice' is correct (58.52*12/100 = 7.6076). But, this resulting penny difference with Total Amount (66.14-7.61-58.52 = 0.01) and also noticed Online Invoice is posted to GL. So we need to understand why we are getting a penny added with online invoice, which is incorrect

Pls. note we have 'Multi Currency is turned on'
