float64 seems is not working with the latest version

[Summer-D]

package main

import (
	"fmt"
	"github.com/caarlos0/env/v6"
	"os"
)

type config struct {
	test float64   `env:"YYYY" envDefault:"1.531"`
	Hostname       string `env:"HOSTNAME" envDefault:"unknown"`
}

func main() {
	os.Clearenv()
	tos := func(v interface{}) string {
		return fmt.Sprintf("%v", v)
	}
	cfg := config{}
	float_str := tos(1.54444)
	fmt.Println(float_str)
	os.Setenv("HOSTNAME", "NONNONO")
	os.Setenv("YYYY", float_str)
	if err := env.Parse(&cfg); err != nil {
		fmt.Println("%+v\n", err)
	}

	fmt.Printf("%f\n", cfg.test)
	fmt.Println(cfg)
}

Output:

1.54444
0.000000
{0 NONNONO}

Can anyone help take a look?

env only works on exported fields, and your test field isn't.
