What should I do if I want to generate a random number in the smarty template? Generate in the PHP file and assign values to the template. This is absolutely feasible, but it is too complicated. the following tips will be used to generate random numbers directly in the smarty template.
Now, if you need to generate a random number between and in the smarty template, you can write it as follows:
The code is as follows:
{Math equation = rand (125,324 )

The math class provides three methods related to rounding: Ceil, floor, and round. The functions of these methods correspond to the meanings of their English names. For example, the English meaning of Ceil is the ceiling. This method indicates the rounded up, math

I haven't used the math class for a long time. I cannot remember it clearly, so that I can make mistakes when I read a scjp question. I will refresh my memory today. Remember!

This kind of wrapper, specifically supported by the compiler, is called boxing, so when the built-in data type is used as an object, the compiler will box the built-in type into a wrapper class. Similarly, the compiler can also disassemble an object into a built-in type. The number class belongs to the Java.lang package.Here is an instance that uses an Integer object:Test.java File Code:public class test{public static void Main (String args[]) {Integer x = 5;x = x + 10;SYSTEM.OUT.BJRONGJINHUIYIN
Here is an instance that uses an Integer object:Test.java File Code:public class test{ public static void Main (String args[]) {Integer x = 5;x = x + 10;SYSTEM.OUT.PRINTLN (x);}}The results of the above example compilation run as follows:15When x is assigned an integer value, because X is an object, the compiler is boxing the X. Then, to allow X to be added, the X is disassembled.Java Math ClassJava's math

In the process of programming, we often perform mathematical operations on some numbers, such as what we want to ask for absolute or cosine. Do these methods need to be implemented by ourselves? In fact, the math class math class in Java.lang contains methods for performing basic mathematical operations, such as elementary exponents, logarithms, square roots, and trigonometric functions.
