qubit math

The first few sections are really tired, so let's start with something simple and easy to understand.A math package math package mainly deals with mathematical-related operations.Constant MATH.E # Natural constant EMath.PI # pi PiArithmetic function Math.ceil (x) # Rounding up the x, such as x=1.2, returns 2Math.floor (x) # rounding x down, such as x=1.2, returns 1Math.pow (x, y) # exponential operation, ge

4.2 Common mathematical functionsThe methods in the math class are divided into three categories: trigonometric functions, exponential function Methods , and service methods . Service methods include rounding, minimum, maximum, Absolute and random methods. In addition to these methods, the math class provides two useful double constants, pi (π) and E (base of natural logarithm). You can use both variables i

Java NumberBuilt-in data type: Byte int long short double, etc.int i = 10；float i = 10.5f;In practice, it is often encountered using objects rather than built-in data types, and wrapper classes (Integer Long Double Float Short) are subclasses of abstract class numberWhen the built-in data type is used as an object, the compiler will box the built-in type into a wrapper classclass Test{ public static void main(String[] args){ Integer i = 10; i = i + 10; System.out.println(

Introduction to using JavaScript Math. ceil () Functions Math. ceil (x) -- returns the smallest integer greater than or equal to the number parameter (take the entire function) and rounds up the number. The following is a good example. If you are interested, refer Math. ceil (x) -- returns the smallest integer greater than or equal to the number parameter (tak

Introduction to the Math object1:math ObjectThe Math object is used to perform mathematical tasks. It is not a class of objects like Date and String, so there is no constructor for Math (). You do not have to create it, and you can invoke all of its properties and methods by using
