Use Java's Math.min() function to compare the size of two numerical values and return the smaller value
When developing Java applications, sometimes we need to compare the size of two numerical values and return the smaller value That number. Java provides the Math.min() function to implement this function.
The Math.min() function is a static method of the Java Math class. It is used to compare the size of two values and return the smaller number. Its syntax is as follows:
public static int min(int a, int b) public static long min(long a, long b) public static float min(float a, float b) public static double min(double a, double b)
Among them, the Math.min() function can accept two values as parameters and return the smaller number based on the relationship between the two values. The data type of the return value depends on the data type of the parameter.
Here is a simple example that demonstrates how to use the Math.min() function to compare two integers and return the smaller value:
public class MathMinExample { public static void main(String[] args) { int a = 10; int b = 5; int result = Math.min(a, b); System.out.println("较小的数是:" + result); } }
In this example, we declare two Integers a and b and give them initial values 10 and 5. We then use the Math.min() function to compare a and b and assign the returned smaller value to the variable result. Finally, we use the System.out.println() function to output the results to the console.
Run the above code, the output result is:
较小的数是:5
We can also use the Math.min() function to compare two floating point numbers and return the smaller value. The example is as follows:
public class MathMinExample { public static void main(String[] args) { float a = 1.5f; float b = 2.8f; float result = Math.min(a, b); System.out.println("较小的数是:" + result); } }
In this example, we declare two floating point numbers a and b and give them initial values 1.5 and 2.8. We use the Math.min() function to compare a and b and assign the returned smaller value to the variable result. Finally, we use the System.out.println() function to output the results to the console.
Run the above code, the output result is:
较小的数是:1.5
Through the above example, we can see that the usage of Math.min() function is very simple. It provides a convenient way to compare two numerical values and return the smaller number.
To summarize, we can use Java's Math.min() function to compare the size of two values and return the smaller value. Whether it is an integer or a floating point number, using the Math.min() function is a simple and effective method. When writing a Java application, if you encounter a situation where you need to compare two values and return the smaller value, you can consider using the Math.min() function.

mPDF
mPDF is a PHP library that can generate PDF files from UTF-8 encoded HTML. The original author, Ian Back, wrote mPDF to output PDF files "on the fly" from his website and handle different languages. It is slower than original scripts like HTML2FPDF and produces larger files when using Unicode fonts, but supports CSS styles etc. and has a lot of enhancements. Supports almost all languages, including RTL (Arabic and Hebrew) and CJK (Chinese, Japanese and Korean). Supports nested block-level elements (such as P, DIV),
