Range -1038 to 1038-1, 1 ⇐ p ⇐ 1000, 0 ⇐ s ⇐ p
Default p is 1000, s is 0
Error Handling If the scale of a value is greater than the declared scale, it is rounded to the specified number of fractional digits
Special Values The special case-insensitive value 'NaN' (not-a-number) is allowed
Standards ANSI SQL
