How to convert a string to integer in Puppet?

  • 772

I want to check whether the content of a variable is an odd number. But I need an integer for it.

$ip_array = split($ipaddress, '.')
$odd_ip = $ip_array[3] % 2

if $odd_ip == 1 {
  notice("is odd")
}

Is there an easy way to convert a string to integer?

  1. You can do this:

    $n_timeout = 0 + $timeout

  2. I've taken to using the scanf function in stdlib.

    An example of this:

    $ram = scanf("${::memorysize_mb}", "%i")

    This requires puppet >= 3.7.5

  3. Your code will work exactly as defined; Puppet implicitly converts strings and integers as appropriate for the comparison operator being used.

  4. Puppet 4: $odd_ip = Integer($ip_array[3]) % 2
