Answer 1

package main

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

func main() {
	str := "2.809 -36.91 21.487 -493.808 5034.7001"
	tokens := strings.Fields(str)
	floats := make([]float64, len(tokens))

	for i, token := range tokens {
		f, err := strconv.ParseFloat(token, 64)
		if err != nil {
			fmt.Println("Error parsing float:", err)
			continue
		}
		fmt.Println(f)
		floats[i] = f
	}

	fmt.Println(floats)
}



/*
