v.wrap This object shifts incoming values into a limited range in a few different ways. This object shifts incoming values into a limited range in a few different ways. It takes one parameter (the limit point) and has two options: reflect and signed. The limit point parameter defines the limits of the possible output values. If signed is 1, the limits are ± the limit point. If signed is 0 the limits are 0 and the limit point. If reflect is 1, then when a limit point is surpassed, the output values reverse direction. If reflect is 0, then when a limit point is surpassed, the output value wraps to the opposite limit point. This behaviour is continuous across the zero point. That is to say that unlike a modulus operator or a remainder calculation, the behaviour is not inverted at the transition from negative to positive.
