484	FloatField with decimal_places but not max_digits causes mysql error.	mmarshall	Adrian Holovaty	"A FloatField that uses {{{decimal_places}}} without {{{max_digits}}} results in using {{{numeric(None, 2)}}}.  This causes an error in mysql (at least.)

I can see two ways to fix this:

 * Update the docs with this info and/or throw a helpful error message.

 * Set the max_digits to the maximum possible.  (255-decimal_places, on mysql at least.)

Note that the same thing also happens when you have {{{max_digits}}} without {{{decimal_places}}}.
