Numeric Types
Of all built-in data-types, Numeric Types are those dedicated to the representation of all kinds of numbers.
FreeBASIC supplies several numeric data types for handling numbers in various representations.
Of these, integer types represent only integer numbers (positive, negative, and zero), and floating-point types represent real numbers.
Integer types
Integer types are those that represent only integer numbers:
- Signed integer types:
- Unsigned integer types:
Floating-point types
Floating-point types are those that represent real numbers:
Pseudo-integer types
Other types that also represent but indirectly integer numbers:
Pointer types
Pointers are types whose values (uinteger) are addresses in memory (they are said to 'point' to this memory).
The type of data that is pointed to depends on the type of pointer (an Integer Pointer points to Integer data).
Pointers are declared like any other variable, with the suffix pointer or ptr following the type name:

(*) INTEGER, UINTEGER, and ENUM data types vary with platform, matching the size of POINTER.
