Operators

Usage 3: Variables associated with dynamic and input text fields have the data type String. In
the following example, the variable

deposit

is an input text field on the Stage. After a user

enters a deposit amount, the script attempts to add

deposit

oldBalance

. However,

because

deposit

is a String data type, the script concatenates (combines to form one string)

the variable values rather than summing them.

var oldBalance:Number = 1345.23;
var currentBalance = deposit_txt.text + oldBalance;
trace(currentBalance);

For example, if a user enters 475 in the deposit text field, the

trace()

function sends the

value 4751345.23 to the Output panel. To correct this, use the

Number()

function to convert

the string to a number, as in the following:

var oldBalance:Number = 1345.23;
var currentBalance:Number = Number(deposit_txt.text) + oldBalance;
trace(currentBalance);

The following example shows how numeric sums to the right of a string expression are not
calculated:

var a:String = 3 + 10 + "asdf";
trace(a); // 13asdf
var b:String = "asdf" + 3 + 10;
trace(b); // asdf310

+= addition assignment operator

expression1

expression2

Assigns

expression1

the value of

expression1

expression2

. For example, the following

two statements have the same result:

x += y;
x = x + y;

This operator also performs string concatenation. All the rules of the addition (+) operator
apply to the addition assignment

(+=)

operator.

Availability:

ActionScript 1.0; Flash Lite 1.0

Operands

expression1 :

Number

- A number or string.

expression2 :

Number

- A number or string.

Returns

Number

- The result of the addition.
