sprintf precision modifiers

The manual for sprintf http://www.php.net/manual/en/function.sprintf.php gives a nice introduction to the idea of the different formatting options. But, the reader is referred to the examples to see the different ways that you can format a number. Is there a better resource than this for formatting codes in sprintf ? I think that the annotations are great, but you shouldn't have to rely on these afterthoughts for your information (I didn't see how I could limit the trailing zeroes until I got to the annotations). Something tells me that for C programmers, formatting output like this is old hat, but for those of us who are just getting our feet wet in programming, there should be a more exhaustive reference as to what can be done... is there any such reference?
