Data type is a fundamental element of any programming language. Currently HBBR Basic supports following simple types as well strings and as arrays of simple types.

List of supported simple types:

Boolean type represents logical values True and False. It is used to perform logical operations (not bitwise!).

Example:

Dim boolVar As Boolean

Const boolConst As Boolean = True

Dim boolArray(1 To 2 ) As Boolean

Sub boolSub( ByVal boolArg As Boolean)

SByte type can be use to represent signed 8 bit value from -128 to 127

Example:

Dim sbyteVar As SByte

Const sbyteConst As SByte = &b11111111

Dim sbyteArray(1 To 2 ) As SByte

Sub sbyteSub( ByVal sbyteArg As SByte)

Byte type can be use to represent unsigned 8 bit value from 0 to 255.

Example:

Dim byteVar As Byte

Const byteConst As Byte = &b11111111

Dim byteArray(1 To 2 ) As Byte

Sub byteSub( ByVal byteArg As Byte)

Short type represents singed 16 bit value from to -32768 to 32767.

Example:

Dim shortVar As Short

Const shortConst As Short = &hFFFF

Dim shortArray(1 To 2 ) As Short

Sub shortSub( ByVal shortArg As Short)

UShort type represents unsigned 16 bit value from 0 to 65535.

Example:

Dim ushortVar As UShort

Const ushortConst As UShort = &hFFFF

Dim ushortArray(1 To 2 ) As UShort

Sub ushortSub( ByVal ushortArg As UShort)

Integer type represents singed 32 bit value from to -2147483648 to 2147483647.

Example:

Dim integerVar As Integer

Const integerConst As Integer = &hFFFFFFFF

Dim integerArray(1 To 2 ) As Integer

Sub integerSub( ByVal integerArg As Integer)

Wikipedia: Integer datatype

UInteger type represents usinged 32 bit value from 0 to 4294967295.

Example:

Dim uintegerVar As UInteger

Const uintegerConst As UInteger = &hFFFFFFFF

Dim uintegerArray(1 To 2 ) As UInteger

Sub uintegerSub( ByVal uintegerArg As UInteger)

Single type represents floating point values from -3.402823E38 to 3.402823E38 .

Example:

Dim singleVar As Single

Const singleConst As Single = 1.0

Dim singleArray(1 To 2 ) As Single

Sub singleSub( ByVal singleArg As Single)

Floating operation require runtime MOD file with built-in math support. If code is compiled with the runtime without math support linker will report errors while trying to locate runtime floating point support functions.
