Precision is the total number of digits, scale is the number of digits
to the right of the decimal point.  So the above (4,2) means numbers
like XX.XX --- and obviously 10 fits, 101 doesn't.  Your previous
example of (3,3) means numbers like .XXX --- no integer will fit,
but fractions will.  I see no bug here...
