PostgreSQL Data Types - NUMERIC and DECIMAL
Versions: PostgreSQL 8.x and 7.x
| PostgreSQL - NUMERIC | |
|---|---|
| Syntax | NUMERIC[(p[,s])] |
| Data | Fixed-point numeric data |
| Parameters | p is the maximum number of all digits (both sides of the decimal point), s is the maximum number of digits after the decimal point |
| 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 |
DECIMAL is identical to NUMERIC
