Go Type Casting

Type casting means conversion of a variable from one data type to another. The value may be lost when large type is converted to a smaller type.

Go Type Conversion Example

     package main
import (
   "fmt"
   "strconv"
)
func main() {

   var i int = 10
   var f float64 = 6.44
   var str1 string = "101"
   var str2 string = "10.123"

   fmt.Println(float64(i))
   fmt.Println(int(f))

   newInt, _ := strconv.ParseInt(str1, 0, 64)
   fmt.Println(newInt)

   newfloat, _ := strconv.ParseFloat(str2, 64)
   fmt.Println(newfloat)
}

    

Output:
