I think we can just change this to use the -1 precision:

args = append(args, "-i", strconv.FormatFloat(p.PingInterval, 'f', -1, 64))

It still will require users to specify an even value, but I think it is better than switching on arch.

args = append(args, "-i", strconv.FormatFloat(p.PingInterval, 'f', -1, 64))
}
if p.Timeout > 0 {
switch runtime.GOOS {
case "darwin":
args = append(args, "-W", strconv.FormatFloat(p.Timeout*1000, 'f', 1, 64))
args = append(args, "-W", strconv.FormatFloat(p.Timeout*1000, 'f', -1, 64))
