ToBytes()

FixedVector< byte > SystemEx.Numeric.Vec2d.ToBytes

(

)

Converts the vector into a deterministic byte sequence.

This method is used by HashFactory to compute attribute‑driven hashes. The byte layout is stable and platform‑safe, ensuring consistent hashing across devices and backends.

Implements SystemEx.Hash.IHashable< T >.
