Next: User-defined Data Types, Up: Data Types
The standard built-in data types are real and complex scalars and matrices, ranges, character strings, a data structure type, and cell arrays. Additional built-in data types may be added in future versions. If you need a specialized data type that is not currently provided as a built-in type, you are encouraged to write your own user-defined data type and contribute it for distribution in a future release of Octave.
The data type of a variable can be determined and changed through the use of the following functions.
Convert val to data type type.
See also: int8, uint8, int16, uint16, int32, uint32, int64, uint64, double.
Convert from one datatype to another without changing the underlying data. The argument type defines the type of the return argument and must be one of 'uint8', 'uint16', 'uint32', 'uint64', 'int8', 'int16', 'int32', 'int64', 'single' or 'double'.
An example of the use of typecast on a little-endian machine is
x = uint16 ([1, 65535]); typecast (x, 'uint8') => [ 0, 1, 255, 255]See also: cast, swapbytes.
