Integer constants

An integer constant specifies an integer as a signed or unsigned number with a maximum of 19 digits that does not include a decimal point.

The data type of an integer constant is large integer if its value is within the range of a large integer. The data type of an integer constant is big integer if its value is outside the range of a large integer, but within the range of a big integer. A constant that is defined outside the range of big integer values is considered a decimal constant.
