Using operators to manipulate values in expressions 51
Numeric operators
Numeric operators add, subtract, multiply, divide, and perform other arithmetic operations.
The most common use of the increment operator is
i++ instead of the more verbose i = i+1.
You can use the increment operator before or after an operand. In the following example,
age is
incremented first and then tested against the number 30:
if (++age >= 30)
This process is also known as a preincrement. In the following example, age is incremented after
the test is performed:
if (age++ >= 30)
This process is also known as a postincrement. The following table lists the ActionScript numeric
operators:
instanceof
Instance of (finds the class of which the object is an
instance)
