INTEGER

Source: https://www.freebasic.net/wiki/wikka.php?wakka=KeyPgInteger Last revised: 2021-12-13

Standard data type: 32-bit or 64-bit signed integer, same size as SizeOf(Any Ptr).

Syntax

Dim variable As Integer
Dim variable As Integer`<bits>`

Parameters

• bits — A numeric constant expression indicating the size in bits: 8, 16, 32, or 64.

Description

Integer is the main data type FreeBASIC uses for integer math and bitwise operations. It is the default type for number literals.

In the first form Integer is a 32-bit or 64-bit signed whole-number data type, depending on the target platform.

If an explicit bit size is given (the second form), a data type is provided that can hold values from -1LL Shl (bits-1) up to (1LL Shl (bits-1)) - 1. The selected data type is Byte for Integer<8>, Short for Integer<16>, Long for Integer<32> and LongInt for Integer<64>.

Examples

#ifdef __FB_64BIT__
    Dim x As Integer = &H8000000000000000
    Dim y As Integer = &H7FFFFFFFFFFFFFFF
    Print "Integer Range = "; x; " to "; y
#else
    Dim x As Integer = &H80000000
    Dim y As Integer = &H7FFFFFFF
    Print "Integer Range = "; x; " to "; y
#endif

Dialect Differences

• In the -lang fb and -lang fblite dialects, the Integer data type is 32-bit or 64-bit depending on target platform.
• In the -lang qb dialect, the Integer data type is 16-bit, regardless of platform.

Differences from QB

• The ability to select a bit size is new to FreeBASIC.
• The INTEGER type is always 16 bits wide in QB.
