Syntax
expression1 == expression2

Arguments
expression1,expression2: A number, string, boolean value, variable or function.

Returns
Nothing.

Description
Operator (equality); tests two expressions for equality. The result is true if the expressions are equal.
The definition of equal depends on the data type of the parameter:

·	Numbers and boolean values are compared by value and are considered equal if they have the same value

·	String constants are converted to numeric unless both expressions are string constants

·	Variables are assumed to be numeric. Possibly undergoing a conversion

·	Two variables are equal if they have the same numeric value.

Sample
x = 5;
y = 6;

trace(x == y);   // returns (0), false

These examples show the results of operations that compare mixed types.
x = "5"; y = "5";
trace(x == y);   // this works as variables are converted to numbers.
// true
// this works as variables are converted to numbers.

x = "5"; y = "66";
trace(x ==y);
// false
// this works as variables are converted to numbers.

x = "chris"; y = "steve";
trace (x == y);
// true
// unexpected result caused by conversion of both strings constants to numeric (value = 0).
// use 'eq' operator instead.
