请教下字符串转float的问题

route:= this.GetString("route") hight:= this.GetString("hight") bridge:= this.GetString("bridge") oil:= this.GetString("oil") // total:= this.GetString("Total") // var total=hight+bridge+oil // var total=strconv.Atoi(hight)+strconv.Atoi(bridge)+strconv.Atoi(oil) var total, err = strconv.ParseFloat(hight, '10', -1, 32)+strconv.ParseFloat(bridge, '10', -1, 32)

▶ 0003 Failed to build the application: # opms/controllers/financial controllers\financial\financial.go:160:6: err redeclared in this block previous declaration at controllers\financial\financial.go:140:5 controllers\financial\financial.go:160:37: too many arguments in call to strconv.ParseFloat have (string, number, number, number) want (string, int) controllers\financial\financial.go:160:37: multiple-value strconv.ParseFloat() in single-value context controllers\financial\financial.go:160:45: invalid character literal (more than one character) controllers\financial\financial.go:160:77: too many arguments in call to strconv.ParseFloat have (string, number, number, number) want (string, int) controllers\financial\financial.go:160:77: multiple-value strconv.ParseFloat() in single-value context

求教各位大神，如何把字符串的转成float的小数相加后再转换回字符串，谢谢

package main import ( "fmt" "strconv" ) func main() { stringA := "34.56213" stringB := "78.90455" floatA, err := strconv.ParseFloat(stringA, 64) if err != nil { panic(err) } floatB, err := strconv.ParseFloat(stringB, 64) if err != nil { panic(err) } floatSum := floatA + floatB stringSum := strconv.FormatFloat(floatSum, 'f', 5, 64) fmt.Println(stringSum) }
