1. vi. (also n. `wraparound' and v. shorthand `wrap') 1. [techspeak] The action of a counter that starts over at zero or at `minus infinity' (see infinity) after its maximum value has been reached, and continues incrementing, either because it is programmed to do so or because of an overflow (as when a car's odometer starts over at 0). 2. To change phase gradually and continuously by maintaining a steady wake-sleep cycle somewhat longer than 24 hours, e.g., living six long (28-hour) days in a week (or, equivalently, sleeping at the rate of 10 microhertz). This sense is also called phase-wrapping. From Jargon Dictionary
