To PowerBASIC, an Integer is a number with no decimal point (what mathematicians would call whole numbers) with a range of -32,768 to +32,767 ( -2^15 to 2^15 - 1). These values stem from the underlying 16-bit representation of an Integer: 32,768 is 2^15, and are therefore 2 bytes (16-bits) wide. The type-specifier character for Integer is: %.
Integers are identified by following the variable name with a percent sign (eg: var%), or by using the DEFINT statement. For example, if you use this declaration in your program code:
DEFINT I, J, K
…then all variables following this declaration that start with the letter I, J, or K will be an Integer by default. You can also declare an Integer variable using the INTEGER keyword with the DIM statement. For example:
DIM I AS INTEGER
A C/C++ short variable and a Delphi smallint are both equivalent to a PowerBASIC Integer.
Long integers (&)
Quad integers (&&)
