go - How to write isNumeric function in Golang? -


i want check if string numeric. example, "abcd123" should return false. "1.4" or "240" should return true. thinking of using strconv parseint , parsefloat not sure if right way.

i thinking of using strconv parseint , parsefloat not sure if right way.

see example here: https://play.golang.org/p/d53hrs-kil
