Vector data types can use some of the unary operators that are
used with primitive data types, as outlined in the table below. These
operators are not supported at global scope or for objects with static
duration, and there is no constant folding. Each element in the vector
has the operation applied to it.

Note: Unary minus operator - on vector double will
not cause IEEE exception.

expressions in z/OS XL C/C++ Language Reference.
