To address the question in the title - Postgres has a definition in the manual:. The following illustrates the syntax of type CAST: It would be useful for Prisma to provide a core data type Decimal to live alongside Float and Int in order to support arbitrary precision numbers. Al parecer tienes un problema por la parametrizacion del tipo de dato decimal, en postgres la configuracion de este tipo de dato consta de una parte entera (digitos) y la parte decimal (precisión) Ej: DECIMAL(5,2), de los 5 digitos 3 para la parte entera y hasta 2 para la parte decimal 000.00 I need to convert a value of Double Precision to Bigint with PostgreSQL.

Describes the built-in data types available in Postgres.. Postgres has a rich set of native data types available to users. This has been corrected to match the SQL standard, which specifies that the precision is measured in binary digits. In this case, I have lost precision. Precision is the number of digits in a number. The money type has a fixed fractional component that takes its precision from the lc_monetary PostgreSQL localization option. In the context of data types, the following sections will discuss SQL standards compliance, porting issues, and usage. Unlike MySQL, PostgreSQL supports Money Type which stores currency amounts with a fixed fractional precision. How can I make this happen? Users may add new types to Postgres using the DEFINE TYPE command described elsewhere.
