Reserved_Data_Types(3) Built-in reserved Data Types.

DESCRIPTION

The data type names described in the table below are reserved and cannot be used by applications as user-defined type names. The vector data type names defined in vectorDataTypes(3clc), but where n is any value other than 2, 3, 4, 8 and 16, are also reserved.

Type Description
booln A boolean vector.
halfn A 16-bit float vector.
quad, quadn A 128-bit floating-point number and vectors. 
complex half,
complex halfn,
imaginary half,
imaginary halfn

Complex and imaginary 16-bit floating-point scalar and vector. 
complex float,
complex floatn,
imaginary float,
imaginary floatn

Complex and imaginary 32-bit floating-point scalar and vector. 
complex double,
complex doublen,
imaginary double,
imaginary doublen

Complex and imaginary 64-bit floating-point scalar and vector. 
complex quad,
complex quadn,
imaginary quad,
imaginary quadn

Complex and imaginary 128-bit floating-point scalar and vector.
floatnxm An n x m matrix of single precision floating-point values stored in column-major order.
doublenxm An n x m matrix of double precision floating-point values stored in column-major order. 
long double,
long doublen

A floating-point scalar and vector type with at long doublen least as much precision and range as a double and no more precision and range than a quad.
long long, long longn A 128-bit signed integer scalar and vector.
