vec_neg
Purpose
Returns a vector containing the negated value of the corresponding elements in the given vector.
Note: For vector signed long long, this function emulates
the operation. This built-in
function is valid only when -qarch is set to target POWER7® processors or higher.
Syntax
d=vec_neg(a)Result and argument types
The following table describes the types of the returned value and the function arguments.
| d | a |
|---|---|
| The same type as argument a | vector signed char |
| vector signed short | |
| vector signed int | |
| vector signed long long | |
| vector float | |
| vector double |
Result value
This function multiplies the value of each element in the given vector by -1.0 and then assigns the result to the corresponding elements in the result vector.
