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)].

How to convert integers to floating point numbers in Go language

The operating environment of this article: windows10 system, Go 1.11.2, thinkpad t480 computer.

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.
