Description:: Selects an index element of an array or config object. Index 0 denotes the first element, 1 the second, etc.
If index has decimal places it gets rounded down for fractions less than or equal .5, otherwise it gets rounded up.
Groups:: Uncategorised

Example 1:: [1,2,3,4] select 2 - result is 3
Example 2:: position player select 2 - result is Z coordinate of player position (see Position for more details)
Example 3:: (configFile >> "CfgVehicles") select 0

General Barron: 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.; Posted on 27 Sep, 2013
Killzone_Kid: 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; Posted on 30 May, 2014 - 1549
ffur2007slx2_5: 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
