Go Type casting


Type casting is a way to convert a variable from one data type to another data type.

For example, if you want to store a long value into a simple integer then you can type cast long to int. You can convert values from one type to another using the cast operator.
type_name(expression)

Example

Consider the following example where the cast operator causes the division of one integer variable by another to be performed as a floating number operation.
package main

import "fmt"

func main() {
   var sum int = 20
   var count int = 25
   var mean float32
   
   mean = float32(sum)/float32(count)
   fmt.Printf("Value of mean : %f\n",mean)
}

Output

$go run main.go
Value of mean : 0.800000
