Specific DecimalField with max_digits > 15 can be stored but not retrieved on SQLite

[Orazio]

Similar to https://code.djangoproject.com/ticket/33954 but different exception:

Given this model

class Apple(models.Model):
	weight = models.DecimalField(max_digits=16, decimal_places=0)

Trying to store 9999999999999999 (16 digits)

$ python manage.py shell

I made sure to test with the latest commit

Exception is raised here: ​https://github.com/django/django/blob/bad1a18ff28a671f2fdfd447bdf8f43602f882c2/django/db/backends/sqlite3/operations.py#L346

As you might imagine this also fails when say max_digits is 20 and storing 20 nines, and so on. Shouldn't this raise an error when running full_clean() on the object before storing?
