How can I convert a string variable into Boolean, Integer or Float type in Golang?
The following source code snippet shows an abbreviated program with several String variables value parsed in Float, Boolean and Integer.
The parse functions
ParseBool, ParseFloat and ParseInt convert strings to values. Hence String variable values getting stored as Boolean, Float and Integer in respective data types.
Example
package main
import (
"fmt"
"reflect"
"strconv"
)
func main() {
fmt.Println("\nConvert String into Boolean Data type\n")
str1 := "japan"
fmt.Println("Before :", reflect.TypeOf(str1))
bolStr,_ := strconv.ParseBool(str1)
fmt.Println("After :", reflect.TypeOf(bolStr))
fmt.Println("\nConvert String into Float64 Data type\n")
str2 := "japan"
fmt.Println("Before :", reflect.TypeOf(str2))
fltStr,_ := strconv.ParseFloat(str2,64)
fmt.Println("After :", reflect.TypeOf(fltStr))
fmt.Println("\nConvert String into Integer Data type\n")
str3 := "japan"
fmt.Println("Before :", reflect.TypeOf(str3))
intStr,_ := strconv.ParseInt(str3,10,64)
fmt.Println("After :", reflect.TypeOf(intStr))
}
