BUt take this (actual) example: I recently found an entry on a site which listed interesting facts about various numbers: 30.48 .... By convention, the number of inches in a foot. Hmm. Seemed to me like a typo (which it was, of course.) But following the logic used by David, what I should have done was assume that the site didn't mean what it seemed to mean by the numeral "30.48", and in fact it meant that to denote 12. Or maybe, it meant "foot" to denote a yard, or a meter; or, maybe, that it meant "inch" to denote centimeter. None of which seem like sensible strategies to me.
