Integer

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

Syntax

Dim variable As Integer
Dim variable As Integer<bits>

Parameters

• bits

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>.

Remarks

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.

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
