Description

Description:

Performs strict comparison between var1 and var2 and returns true if equal otherwise false.

Some differences between == and isEqualTo:

• Performs case sensitive comparison on Strings
• Doesn't throw error when comparing different types, i.e. ("eleven" isEqualTo 11)
• Can compare Arrays and Booleans
• Can compare Namespaces (As of Arma 3 v1.47)

Syntax

Syntax:

var1 isEqualTo var2

Parameters:

var1: Anything

var2: Anything

Return Value:

Boolean

Examples

Example 1:

_arr1 = [1,[2,[3]]]; _arr2 = [1,[2,[3]]]; if (_arr1 isEqualTo _arr2) then {hint "Arrays match!"}

Example 2:

if (a isEqualTo b) then {hint "a is equal to b"}; if !(a isEqualTo b) then {hint "a is not equal to b"};

The behavior of "var1 isEqualTo var2" is pretty much equivalent to "var1 in [var2]", plus the ability to compare arrays, and slightly better performance.

Simply put, "isEqualTo" is a binary comparison. Therefor it is very fast but only accepts 100% identical matches. In some other languages this is known as "===" instead of "==".

A faster, case-sensitive alternative to BIS_fnc_areEqual using isEqualTo: KK_fnc_allEqual = { private ["_arr", "_first"]; _arr = []; _first = _this select 0; for "_i" from 0 to count _this - 1 do { _arr pushBack _first; }; _arr isEqualTo _this }; // Example [[1,2],[1,2],[1,3]] call KK_fnc_allEqual; //false

Array "compare" implementation using isEqualTo, a faster, case-sensitive alternative to BIS_fnc_arrayCompare: KK_fnc_compare = { _this select 0 isEqualTo (_this select 1) }; // Example [[1,2,3],[1,2,3]] call KK_fnc_compare; //true
