It should go without saying that the "text" char array you suggest must already exist, and be at least one char longer than the longest string you expect (I'd make it twice as long).

And use snprintf(3) instead. Bad People (or you) will try to overrun the buffer if you don't prevent it. (Not likely with a %f format spec, but even if you trust the dealer, you always cut the cards.)
