Description

Description:: Returns whether one value is not equal to another. String comparison is case-insensitive (e.g "STRINGtext" != "stringTEXT" // returns false - strings are equivalent).
⚠
a and b types must match: comparing e.g String with Number is invalid.
Groups:: Variables Math

Syntax

Syntax:

a != b

Parameters:

a:

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

b: identical to a's type

Return Value:

Boolean - true if a is different from b, false otherwise

Examples

Example 1:: if (_counter != 4) then { hint "The counter is not equal to the number 4"; };
Example 2:: if (vehicle player != player) then { hint "you are in a vehicle"; } else { hint "you are on foot"; };
Example 3:: if (fuel truck1 != 1) then { hint "Truck1 has less than a full tank of fuel."; };
Example 4:: if (alive _unit1 != alive _unit2) then { hint "One of the units is dead while another is alive" };
