Synopsis

Not equal operator on values.

Syntax

Exp₁ != Exp₂

Types

Exp₁	Exp₂	Exp₁ != Exp₂

Description

Yields true if both arguments are not identical and false otherwise.

Examples

Introduce two variables X, Y and Z and force them to be of type value:

rascal>value X = "abc";
value: "abc"
rascal>value Y = "abc";
value: "abc"
rascal>value Z = 3.14;

Now compare X and Y for inequality:

rascal>X != Y;

and X and Z:

rascal>X != Z;
bool: true
