UNO provides a set of predefined, simple types which are listed in the following table:

UNO Type	Description
void	Empty type, used only as method return type and in any.
boolean	Can be true or false.
byte	Signed 8-bit integer type (ranging from -128 to 127, inclusive).
short	Signed 16-bit integer type (ranging from −32768 to 32767, inclusive).
unsigned short	Unsigned 16-bit integer type (deprecated).
long	Signed 32-bit integer type (ranging from −2147483648 to 2147483647, inclusive).
unsigned long	Unsigned 32-bit integer type (deprecated).
hyper	Signed 64-bit integer type (ranging from −9223372036854775808 to 9223372036854775807, inclusive).
unsigned hyper	Unsigned 64-bit integer type (deprecated).
float	IEC 60559 single precision floating point type.
double	IEC 60559 double precision floating point type.
char	Represents individual Unicode characters (more precisely: individual UTF-16 code units).
string	Represents Unicode strings (more precisely: strings of Unicode scalar values).
type	Meta type that describes all UNO types.
any	Special type that can represent values of all other types.

The chapters about language bindings Java Language Binding, C++ Language Binding, OpenOffice Basic and Automation Bridge describe how these types are mapped to the types of your target language.
