What ActionScript 3.0 data type is used for storing floating-point numbers?

In ActionScript 3.0, the data type used for storing floating-point numbers is "Number." This data type can represent both integer values and decimal values, making it versatile for various programming needs, such as performing calculations that require precision.

The "Number" data type follows the IEEE 754 standard for floating-point arithmetic, which means it can handle a wide range of values, including very small and very large numbers, as well as special values like NaN (not a number) and positive and negative infinity. This flexibility is particularly advantageous in graphical programming and animations where precise positioning and transformations often involve non-integer values.

Other choices represent different data types: "String" is used for storing text, "Boolean" is for true/false values, and "Null" represents the absence of a value. Each of these data types serves its own unique purpose, but they do not cater to the requirements of handling floating-point numbers as "Number" does.
