Go language type conversion

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
