Flash ActionScript Data Type 80 codes

1 ActionScript available scopes

2 Add two number values in the middle of a string concatenation statement

3 Adding an int and a float, assigning to a float

4 Adding strings and numbers

5 An example of a for statement that outputs the numbers from 0 to 999

6 Call the numbers toString() method This is the preferred way

7 Casting to a Number

8 Checking for Null Values

9 Class Level (Static) Variables and Methods are accessed by using the class name followed by the object name

10 Combining operators with assignment will use the left-hand side of the expression as the first operand

11 Construct string object from a date type value

12 Contains reusable methods for operations pertaining to int values

13 Convert null to number

14 Convert null to string

15 Convert numeric literals to uint objects and output the string representations in base-16 (hexadecimal) format

16 Convert numeric literals to uint objects and output the string representations in base-2 (binary)

17 Convert undefined to Number

18 Convert undefined to string

19 Converting a string containing only numerical data

20 Converting to a Number with Precision

21 Creates a variable named width, of type int, and assigns it the value 25

22 Creating a Separate Copy of an variable

23 Dealing with Infinite Values

24 Decimal Numbers

25 Display a sequence of square roots

26 Dividing an int and an int, upgraded to float since the result is not a whole number, and the left-hand side doesnt specify a ty

27 Function-Level Variables and Functions

28 Handling Minimum and Maximum Values

29 Hexadecimal literals start with 0x

30 If omitted, the radix is assumed to be 10, unless the string starts with 0x, 0X, or 0

31 If statement ladder

32 If you convert the string values of true and false, they will both convert to the Boolean true value because both string values

33 If you omit the second parameter, ActionScript attempts to parse the number value using the most appropriate base

34 Include the number variable in a string expression This will implicitly convert the number to a String

35 Instance Level Variables and Methods are independent for each instance of the class

36 Instance Method Scope

37 It is a good practice to initialize your variables to null when you dont have any other specific value to assign to them

38 Minimum and Maximum Values for uint and int

39 Not a Number

40 Number and int data types have a toString( ) method available

41 Numbers preceding the value that is converted to a string will be added rather than concatenated

42 Numeric Conversions

43 Numeric value of 0 can be converted to a Boolean false, and any nonzero value will be converted to true

44 Octal is treated as a decimal number, not an octal number

45 Octal literals start with 0

46 Once a variable has been declared, you can assign a value to it using a simple assignment statement with an equals sign

47 Overriding Variables

48 Parse number values from strings with bases other than 10 using the parseInt() function

49 Parse the numbers from the string base-10

50 Parse the numbers from the string base-16 (hexadecimal)

51 Parse the numbers from the string in base-2 (binary)

52 ParseFloat()

53 ParseInt()

54 Perform operations using variables

55 Read and write to a variable

56 Static Method Scope

57 The default value for an unassigned variable of type Number is NaN

58 The int type is perfect for counters, and is frequently found in for loops

59 The undefined value represents the absence of data for variables, parameters, and return values without a specified type annotat

60 To check whether a value is a valid number, use isNaN( )

61 To declare a variable using strong typing

62 To declare the data type of a variable, use the colon operator right after the name of the variable

63 ToExponential()

64 ToFixed()

65 ToPrecision()

66 Trying to cast any other value will result in a nasty NaN (Not a Number) value being assigned instead

67 Use int() method to convert boolean value to integer

68 Use int() method to convert float number to integer

69 Use int() to convert string to integer

70 Use Number type variable in for loop

71 Use Number() to convert string to a float number

72 Use String() to convert integer to string

73 Use the this keyword when referring to an instance variable with the same name as a function variable

74 Using Access Controls

75 Using Untyped Variables with the Wildcard () Data Type

76 When the number is treated base-10, conversion stops when a non-numeric character is encountered

77 Working with Number Instances

78 You can also declare the variable and assign a value, or initialize the variable, all on one line

79 You can also use exponential notation to declare numbers

80 You can declare several variables on a single line
