how to set an exact shipping cost with tax

[bartman]

We need to set an exact shipping cost of £1.95 including tax. as we are based in the uk the shipping is taxable at 20% as its a service we offer.

so in prestashop it only lets me set the shipping cost - the tax rate to two decimal places

to achieve as shipping rate of £1.95 it needs to be set to 1.625 as 1.625 x 1.2 = 1.95

but presta shop will only let me set the cost at 1.62 or 1.63 so 1.62 get rounded down to 1.94 and 1.63 get rounded up to 1.96. not what we want.

have thought about going into the db and aletring the table. but any other ideas would be appreciated


thanks
