INTEGER
Standard data type: 32-bit or 64-bit signed, same size as KeyPgSizeof SizeOf(KeyPgAny Any KeyPgPtr Ptr)
Syntax:
Parameters:
bits
A numeric constant expression indicating the size in bits of integer desired. The values allowed are 8, 16, 32 or 64.
Description:
32-bit or 64-bit signed whole-number data type, depending on the platform.
Integer is the main data type FreeBASIC uses for integer math and bitwise operations. It is the default type for number literals.
If an explicit bit size is given, a data type is provided that can hold values from -1LL KeyPgOpShiftleft Shl (bits-1) up to (1LL KeyPgOpShiftleft Shl (bits-1)) - 1.

If an explicit bit size is given, a data type is provided that can hold values from -1LL KeyPgOpShiftleft Shl (bits-1) up to (1LL KeyPgOpShiftleft Shl (bits-1)) - 1.
Examples:
#if __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
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 CompilerOptlang -lang fb and CompilerOptlang -lang fblite dialects, the Integer data type is 32-bit.
- In the CompilerOptlang -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.
