Does not work with the types [[Boolean]] and [[Array]].
 
i.e. the arguments:
 
? MyBoolean <nowiki>==</nowiki> true : [[hint]] "This is a test."
 
and
 
? MyArray <nowiki>==</nowiki> [] : [[hint]] "This is a test."
 
...will cause errors.
 
Instead of the first line use:<br>
? MyBoolean : [[hint]] "This is a test."
 
The workaround for the second line is:<br>
? ([[count]] MyArray) <nowiki>==</nowiki> 0 : [[hint]] "This is a test."

In ArmA3 ver 1.16 for case sensitive comparison, array comparison and boolean comparison we can use [[switch do]]. e.g.
<code>
switch (_var0) do {
        case (_var1) : {true};
        default {false};
</code>
For script comparison we need to detect whether scripts are running in advance, then compose both into string:
<code> if(scriptdone _var0) then [{false},{(str _var0) == (str _var1)}];</code>
It is recommended to use [[isEqualTo]] for all types comparison, which is more functional and as fast as operator.
For multiple comparisons:
<code>
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
</code>
And we can use such workaround instead of using [[BIS_fnc_arrayCompare]] or [[BIS_fnc_areEqual]]

In OFP v1.96, comparison of strings is not case sensitive. Example : "STRINGtext" == "stringTEXT" returns true.

In ArmA3 ver 1.16 for case sensitive comparison, array comparison and boolean comparison we can use switch do. e.g. switch (_var0) do { case (_var1) : {true}; default {false}; 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
