Converting []uint8 to float64

go, type-conversion

Solution

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\n", f) // 0.001255

Problem

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]) ```
