When combined with the count command, this can be used to read all entries out of a config; even when you don't know exactly how many entries there will be. See the notes under count for more info.

Rounding of fractions with select is not the same as when you use round command: _roundThis = 0.5; hint str ([0,1] select _roundThis); //0 hint str round _roundThis; //1

In ArmA3 ver 1.18, Boolean type supported. Which true defaulted as 1 and false as 0. [0,1] select (56 > 40) // 1 [0,1,2] select ((!isNil "v") && false) // 0

Usually when select tries to pick up element out of range, Arma throws "division by zero" error. However there are exceptions. Basically as long as index of element you are selecting is less then or equal to array size, you will get no error. [] select 0; //ok, result is nil [1,2,3] select 3; //ok, result is nil [1,2,3] select 4; //division by zero
