Vector built-in functions

Individual elements of vectors can be accessed and manipulated by using the vector built-in functions. You must enable the vector support to use these built-in functions. This section provides description of the supported vector built-in functions.

This section uses pseudo code description to represent the built-in function syntax, as shown below:

d = builtin_name(a, b, c)

In the description,

d represents the return value of the built-in function.
a, b, and c represent the arguments of the built-in function.
builtin_name is the name of the built-in function.

For example, the syntax for the built-in function with the prototype of vector double vec_xl(long, double*) is represented by d = vec_xl(a, b).

Allowed data types for the return value and arguments of the built-in functions are provided in the tables after the description of the built-in functions.

Note: The tables only list the supported vector data types with the vector keyword. The same data types with the __vector keyword, which is the alternative spelling of vector, are also supported.
