S3L Array Attributes

A principal attribute of S3L arrays is rank--the number of dimensions an array has. For example, an S3L array with three dimensions is called a rank-three array. S3L arrays can have up to 31 dimensions.

An S3L array is also defined by its extents, its length along each dimension of the array and its type, which reflects the data type of its elements. S3L arrays can be of the following types:

• S3L_integer (4-byte integer)

• S3L_long_integer (8-byte integer)

• S3L_float (4-byte floating point number)

• S3L_double (8-byte double precision floating point number)

• S3L_integer (4-byte integer)

• S3L_complex (8-byte complex number)

• S3L_double_complex (16-byte complex number)

The C and Fortran equivalents of these array data types are described in Chapter 4, Sun S3L Data Types.
