8.2. Monetary Types

Note: The money type is deprecated. Use numeric or decimal instead, in combination with the to_char function.

The money type stores a currency amount with a fixed fractional precision; see Table 8-3. Input is accepted in a variety of formats, including integer and floating-point literals, as well as "typical" currency formatting, such as '$1,000.00'. Output is generally in the latter form but depends on the locale.
