将[] uint8转换为float64

Question

What is the best way to handle an http resp.Body which is formatted as []uint8 and not as JSON? I would like to convert the bytes into a float64.

This is the returned value response:

value : %!F([]uint8=[48 46 48 48 49 50 53 53 50 49])

Answer 1

Try using ParseFloat from the strconv package (play):

b := []uint8{48, 46, 48, 48, 49, 50, 53, 53, 50, 49}

f, err := strconv.ParseFloat(string(b), 64)

if err != nil { 
    // Handle parse error
}

fmt.Printf("%f
", f) // 0.001255
