The Math object is different from the above object. It can be said to be a common mathematics class, which has many mathematical methods used for various mathematical operations, but Math objects do not need to be constructed, you can directly use
Math is a built-in js object and does not need to be created, so it does not need to be instantiated. It only has static attributes and static method Math object attributes: 1. E attribute is approximately 2.718. 2. The LN2 attribute returns the
BC is an advanced tool for mathematical operations and contains a number of options for performing floating-point arithmetic and applying some advanced functions:[Email protected] ~]# echo 3*2.12 | Bc6.36[[email protected] ~]# n=54[[email protected]
In flash, the math class is a very common class. Through mathematical computation, we can achieve a lot of wonderful results. Here we will start from the most basic learning and add a math knowledge.
Let's take a look at the math class provided in
