# download package with go mod
go get github.com/changsongl/isodd
# import package in your program
import "github.com/changsongl/isodd"// some examples
var strNum1 string = "1"
isOdd, err := isodd.String(strNum1) // true, nil
var strNum2 string = "0"
isOdd, err := isodd.String(strNum2) // false, nil
var num int64 = -1
isOdd := isodd.Int64(num) // true
var num int64 = 0
isOdd := isodd.Int64(num) // false
// float type: it convert float to int type and
// then check whether it is odd
var num float32 = -1.32
isOdd := isodd.Float32(num) // true
var num float32 = 0
isOdd := isodd.Int64(num) // false
