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:

10 6 101 10.123
