You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: float64_slice.go
    path of file: ./repos/scan4all/vendor/github.com/spf13/pflag
    
    the code of the file until where you have to start completion: package pflag

import (
	"fmt"
	"strconv"
	"strings"
)

// -- float64Slice Value
type float64SliceValue struct {
	value   *[]float64
	changed bool
}

func newFloat64SliceValue(val []float64, p *[]float64) *float64SliceValue {
	isv := new(float64SliceValue)
	isv.value = p
	*isv.value = val
	return isv
}

func (s *float64SliceValue) Set(val string) error {
	ss := strings.Split(val, "
    
func float64SliceConv(val string) (interface{}, error) {
	val = strings.Trim(val, "[]")
	// Empty string would cause a slice with one (empty) entry
	if len(val) == 0 {
		return []float64{}, nil
	}
	ss := strings.Split(val, ",")
	out := make([]float64, len(ss))
	for i, d := range ss {
		var err error
		out[i], err = strconv.ParseFloat(d, 64)
		if err != nil {
			return nil, err
		}

	}
	return out, nil
}
