That will fail for the scenario that Christope Pettus pointed out. California
is not the only state with sales tax specified to a quarter point., or even a
tenth of a point as in Missouri, where a local sales tax can be 9.241%, and
equal or exceed 10%, as in Alabama, Arizona, California and Illinois.

It's a good idea to research the domain before deciding on the representation.
