In theory a FutureWarning I guess (returning the array), but in practice, I think we should just give the correct array result. (I don't love returning arrays from scalar constructors, but that is another thing and not for now.) - Sebsatian > ``` > > In 1.24.2, `np.float64(np.array([0.0])` returns the the scalar 0.0. > > If passing arrays to `np.float64()` is intentionally supported, it > seems it would be more consistent for `np.float64(np.array([0.0]))` > to > return `np.array([0.0])`.
