Postgres provides ways to store monetary data, the Numeric type, and its alias, Decimal. These types can store numbers with a very large number of digits, and yet perform calculations exactly.

Postgres also offers a dedicated Money type which stores currency amounts with a fixed fractional precision.
The input can take many forms including integers, floats, and even strings such as ‘$20.00’. The output is also automatically formatted as a currency value.
