rounding total values including and excluding tax

rounding total values including and excluding tax, Need advise on what approach to follow.

We have 2 items:

Total payable value:

Item 1 costs: 4.29

Item 2 costs: 12

Tax:

For item 1 is: 5%

For item 2 is: 12.5%

Ex Vat (calculated from Total value):

Item 1: 4.0857

Item 2: 10.6667

Now the calculations will go:

Item 1: 4.0857 * 5% = 0.204285 (rounded to 2 digits decimal - 0.20)

Item 2: 10.6667 * 12.5% = 1.3333375 (rounded to 2 digits decimal - 1.33)

Total for basket = 16.29 (as ex vat value is calculated from total value)

Total from [login to view URL] + taxes: 4.0857 + 0.204285 + 10.6667 + 1.3333375 = 4.289985 + 12.0000375 = 16.2900225 (rounded to 2 digits: 16.29)

If I loose the precision on calcs (for example I calculate tax value from 2 digit decimal number, ex 4.09 * 5%), it will create chain reaction which will enlarge total value to 16.30 (after rounding), so it will create another set anomalies that will affect total value as well.

Anyone has a good idea?
