Reports true if the given agentset is non-empty, false otherwise.Įquivalent to "count agentset > 0", but arguably more readable. Will not be run (since it can't affect the result). Note that if condition1 is false, then condition2 Reports true if both condition1 and condition2 are Reports the arc cosine (inverse cosine) of the given number. The available color names are listed below.
