The Ingres runtime system provides automatic data type conversion between numeric-type values in the database and the forms system and numeric Ada variables. The standard type conversion rules (according to standard VAX rules) are followed. For example, if you assign a float variable to an integer-valued field, the digits after the decimal point of the variable's value are truncated. Runtime errors are generated for overflow on conversion.

The Ingres money type is represented as long_float, an 8-byte floating-point value.
