The Floor block rounds a single control input down to the nearest integer — the largest whole number that is less than or equal to the input — and writes it to a control output. It is a control-domain math operator with no adjustable parameters.
On every tick it reads the incoming control value, applies the standard-library floor function and stores the rounded value on the output control pin. It holds no state and processes one sample-frame per tick, in step with WaveWarp's sample-per-sample engine.
