Converts the type of each element in a from integer to floating-point single precision and divides the result by 2 to the power of b.
d=vec_ctd(a, b)
The following table describes the types of the returned value and the function arguments.
| d | a | b |
|---|---|---|
| vector double | vector signed int | 0–31 |
| vector unsigned int | ||
| vector signed long long | ||
| vector unsigned long long |
