Decider combinator
The Decider combinator is part of the circuit network and one of three types of combinators available in the game. It is used to make comparisons of signals on the network. Signals can be compared using "is greater than" (>), "is less than" (<) or "is equal to" (=). Input contacts are to the left in the above picture, outputs on the right.
Function
The internal logic process has three steps:
1) Values for each individual input signal(s) (items of the same name) on the red and green wires are summed within the combinator.
2) The combinator GUI specifies a "first" input signal, a comparison (>, <, =), and a "second" input signal or constant.
3) If the comparison returns true, the output is a new signal (any name) with either the same value as "first" input signal, or 1.
The decider combinator can handle special signals.
