How do you tell if a string is numeric in go lang? Here is a go lang example that shows how to determine if a string is a number:

Source: (example.go)

package main
 
import (
   "fmt"
   "strconv"
)
 
func main() {
   fmt.Println(IsNumeric("1"))
   fmt.Println(IsNumeric("12.345"))
   fmt.Println(IsNumeric("NOT"))
}
 
func IsNumeric(s string) bool {
   _, err := strconv.ParseFloat(s, 64)
   return err == nil
}

Output

$ go run example.go
true
true
false
