Go Language Type Conversion

Type conversion is used to convert a variable of one data type to another type. The basic format for type conversion in Go is as follows:

type_name(expression)

type_name is the type, and expression is the expression.

Example

In the following example, an integer is converted to a float, and the result is calculated and assigned to a float variable:

Example

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 output of the above example is:

mean 的值为: 3.400000
