[ic] Easiest way to display price inc VAT/TAX??

[interchange at tvcables.co.uk]

Hi folks,

All prices are stored in the database ex VAT, what is the easiest way to 
DISPLAY prices inc VAT? I found a thread referring to this which 
mentions "$price /= 1.175" (assumes 17.5%), how do I use that???

Thanks,
Andy.
