Integer Part is a control-domain math block that outputs the integer part of its control input — the value with any fractional remainder removed, rounded toward zero, so 3.7 becomes 3 and -3.7 becomes -3. It works purely on control signals, mapping a single control input to a single control output, and has no adjustable parameters.
Each tick it splits the incoming control value into its whole and fractional parts and passes only the whole part to the output. The block is evaluated once per engine tick, one sample-frame at a time, as WaveWarp's sample-per-sample engine advances.
