Number Data Types

< All Topics

INT, LONGINT, and VASTINT represent varying sizes of numbers and varying storage space usage, but otherwise receive identical treatment by the software. INT, LONGINT, and VASTINT values can contain only digits.

The NUMERIC data type represents numbers stored in character form and may therefore contain a leading sign (+, -) or an embedded decimal point, or both. Spaces are permitted before and after the leading sign, but not between digits.
