ActionScript language elements

- subtraction operator

(Negation) -

expression

(Subtraction)

expression1

expression2

Used for negating or subtracting.

Usage 1: When used for negating, it reverses the sign of the numerical

expression

. Usage 2:

When used for subtracting, it performs an arithmetic subtraction on two numerical
expressions, subtracting

expression2

from

expression1

. When both expressions are

integers, the difference is an integer. When either or both expressions are floating-point
numbers, the difference is a floating-point number.

Availability:

ActionScript 1.0; Flash Player 4

Operands

expression1 : Number

- A number or expression that evaluates to a number.

expression2 : Number

- A number or expression that evaluates to a number.

Returns

Number

- An integer or floating-point number.

Example

Usage 1: The following statement reverses the sign of the expression 2 + 3:

trace(-(2+3)); // output: -5

Usage 2: The following statement subtracts the integer 2 from the integer 5:

trace(5-2); // output: 3

The result, 3, is an integer. Usage 3: The following statement subtracts the floating-point
number 1.5 from the floating-point number 3.25:

trace(3.25-1.5); // output: 1.75

The result, 1.75, is a floating-point number.

-= subtraction assignment operator

expression1

expression2

Assigns

expression1

the value of

expression1

expression2

. For example, the following

two statements are equivalent:

x -= y ;x = x - y;

String expressions must be converted to numbers; otherwise,

NaN

(not a number) is returned.
