Returns: A basic_simd object ret where the

i^{th}

element is initialized to the result of cmplx-func(v[i]) for all i in the range [0, V::size()), where cmplx-func is the corresponding function from <complex>.

If in an invocation of cmplx-func for index i a domain, pole, or range error would occur, the value of ret[i] is unspecified.

Remarks: It is unspecified whether errno ([errno]) is accessed.
