Returns a vector by copying the sign of the elements in vector a to the sign of the corresponding elements in vector b.
This function requires the POWER7 architecture.
d=vec_cpsgn(a, b)
The following table describes the types of the returned value and the function arguments.
| d | a | b |
|---|---|---|
| vector float | vector float | vector float |
| vector double | vector double | vector double |
