Description

Description:

Check if a is equal to b. String comparison is case-insensitive - use isEqualTo if case sensitivity is needed.

⚠

a and b types must match: comparing e.g String with Number is invalid.

Parameters:

a:

Introduced in	1.00					1.00				1.08	2.00
Possible Type	Number	Side	String	Object	Group	Structured Text	Config	Display	Control	Location	Diary Record	Namespace	Boolean

Example 2:

"MyRabbit" == "MYRABBIT"; // returns true

For script comparison we need to detect whether scripts are running in advance, then compose both into string:

if (scriptDone _var0) then [{false},{(str _var0) == (str _var1)}];

It is recommended to use isEqualTo for all types comparison, which is more functional and as fast as operator. For multiple comparisons:

fnc_areEqual = { private ["_b", "_var1", "_var2"]; _b = true; for [{ _i = 1 }, { _i < (count _this) && _b }, { _i=_i + 1 }] do { _var1 = _this select (_i-1); _var2 = _this select _i; if (!(_var1 isEqualTo _var2)) then { _b = false; }; }; _b }; ["A","a","a"] call fnc_areEqual; // false

And we can use such workaround instead of using BIS_fnc_arrayCompare or BIS_fnc_areEqual
