Function core::intrinsics::simd::simd_as

pub unsafe extern "rust-intrinsic" fn simd_as<T, U>(x: T) -> U

🔬This is a nightly-only experimental API. (core_intrinsics)

Numerically casts a vector, elementwise.

T and U be a vectors of integer or floating point primitive types, and must have the same length.

Like simd_cast, but saturates float-to-integer conversions (NaN becomes 0). This matches regular as and is always safe.

When casting floats to integers, the result is truncated. When casting integers to floats, the result is rounded. Otherwise, truncates or extends the value, maintaining the sign for signed integers.
