Returns a vector containing the results of performing a negative multiply-sum operation on the given vectors.
This function requires the POWER7 architecture.
d=vec_nmadd(a, b, c)
The following table describes the types of the returned value and the function arguments.
| d | a | b | c |
|---|---|---|---|
| vector float | vector float | vector float | vector float |
| vector double | vector double | vector double | vector double |
The value of each element of the result is the product of the corresponding elements of a and b, added by the corresponding elements of c, and then multiplied by -1.0.
