How to convert integers to floating point numbers in Go language
Go language's method of converting integers into floating point numbers: [float32(int_expression)]. Type conversion is used to convert variables of one data type into variables of another type. The basic format is [type_name(expression)].

Type conversion is used to convert variables of one data type into variables of another type. The basic format of Go language type conversion is as follows:
type_name(expression)
type_name is the type and expression is the expression.
Example
In the following example, the integer type is converted into a floating point type, the result is calculated, and the result is assigned to a floating point variable:
package main import "fmt" func main() { var sum int = 17 var count int = 5 var mean float32 mean = float32(sum)/float32(count) fmt.Printf("mean 的值为: %f\n",mean) }
The above example executes the output result For:
mean 的值为: 3.400000

Go language error handling becomes more flexible and readable through errors.Is and errors.As functions. 1.errors.Is is used to check whether the error is the same as the specified error and is suitable for the processing of the error chain. 2.errors.As can not only check the error type, but also convert the error to a specific type, which is convenient for extracting error information. Using these functions can simplify error handling logic, but pay attention to the correct delivery of error chains and avoid excessive dependence to prevent code complexity.

Use the recover() function in Go to recover from panic. The specific methods are: 1) Use recover() to capture panic in the defer function to avoid program crashes; 2) Record detailed error information for debugging; 3) Decide whether to resume program execution based on the specific situation; 4) Use with caution to avoid affecting performance.

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),
