General

A variation of the random object. fluctuate takes a focus point, a minimum offset from the focus, and a maximum offset from the focus. The result is the range that fluctuate will use to generate random values. The calculated extremes are inclusive. Changing the focus simultaneously changes the upper and lower limits of the randomly generated numbers. If min and max are both positive or both negative, the output will not include the focus.

Input

	bang	in leftmost inlet: trigger random output.
	#	in leftmost inlet: min and max represent fixed values from the focus.
	%	in left inlet: min and max represent a percentage deviation from the focus. (Useful for fluctuations of time). min deviation = focus + (focus * min/100). max deviation = focus + (focus * max/100).
	int	in leftmost inlet: set the focus.
	in1	set the lower limit of the random numbers. Negative values set the lower limit below the focus. Positive numbers set the lower limit above the focus. Actual lower limit depends on the mode (% or #).
	in2	set the upper limit of the random numbers. Negative values set the upper limit below the focus. Positive numbers set the upper limit above the focus. Actual upper limit depends on the mode (% or #).

Arguments

optional

The first argument may be a Symbol (% or #). The remaining arguments are integers: focus, min, max.

Output

	int out left outlet	a random number between (focus + min) and (focus + max), inclusive. If the generated number = previously generated number, no output. If min=max, (focus + min) is output at the next bang and no further output is made until min != max.
	bang out right outlet	if no change between previous output and new value.
