Incorrect Error Message in float64 Method in decode_number.go

[funplusxxx]

Hello,

I was going through the source code of msgpack and noticed a potential issue in the float64 method in the decode_number.go file.

Here is the code snippet:

func (d *Decoder) float64(c codes.Code) (float64, error) {
	switch c {
	case codes.Float:
		n, err := d.float32(c)
		if err != nil {
			return 0, err
		}
		return float64(n), nil
	case codes.Double:
		n, err := d.uint64()
		if err != nil {
			return 0, err
		}
		return math.Float64frombits(n), nil
	}

	n, err := d.int(c)
	if err != nil {
		return 0, fmt.Errorf("msgpack: invalid code=%x decoding float32", c)
	}
	return float64(n), nil
}


In the error message of the last fmt.Errorf, it says "decoding float32", but it should be "decoding float64" as the method is for decoding a float64 value.

The corrected error message should be:

return 0, fmt.Errorf("msgpack: invalid code=%x decoding float64", c)
