Function broadcast¶

`function` broadcast(T) simd ¶

template <size_t N, typename T>
constexpr KFR_INTRINSIC vec<T, N> broadcast(T x) { … }

Broadcast a scalar to all N elements of a vector.

Template parameters
N	Target vector width.

Parameters
x	Scalar value to broadcast.

Returns
	A `vec<T, N>` with every element equal to `x` .

Fully qualified name: kfr::broadcast(T)

template <size_t Nout, typename... Ts, typename C = typename std::common_type<Ts...>::type>
KFR_INTRINSIC vec<C, Nout> broadcast(const Ts&... values)

Broadcasts a pack of scalar values into a vector of length Nout.

The supplied values are repeated cyclically to fill all Nout lanes. The common type of all values is used as the element type.

Template parameters
Nout	Output vector length.
Ts	Input scalar types.
C	Common type of `Ts,` used as the element type.

Parameters
values	Scalar values to broadcast from.

Returns
	A vector of length `Nout` filled by cycling through `values.`

Fully qualified name: kfr::broadcast(const Ts &...)
