Go Program for String to Numeric Conversion
Go Program for String to Numeric Conversion
In Go programming, Built in functions ParseInt and ParseFloat are used to convert string to integer and string to float respectively by importing strconv package.
Simple Go program explains how to convert string into integer and string into float and also with sample output.
package main
import (
"fmt"
"strconv"
)
func main() {
var str1, str2 string
var val1 int64
var val2 float64
var err error
str1 = "13"
str2 = "10.5"
//base 10 and 64 bit integer
val1,err = strconv.ParseInt(str1, 10, 32)
if err==nil {
fmt.Printf("string to int conversion str1 '%s': %d\n", str1, val1)
} else {
fmt.Println(err)
}
val2,err = strconv.ParseFloat(str2, 64)
if err==nil {
fmt.Printf("string to float conversion str2 '%s': %.2f\n", str2, val2)
} else {
fmt.Println(err)
}
}
Output:
$ go build string-to-numbers.go $ ./string-to-numbers string to int conversion str1 '13': 13 string to float conversion str2 '10.5': 10.50« Previous Next »
