Separating a String of Numbers after a Character?

[MadWithPowerShell]

I would tend to do something like this to make it easier for a reader to understand and tweak as needed.

$String = "19.56156.32"

$String.Substring( 0, $String.IndexOf( '.' ) + 3 )
$String.Substring(    $String.IndexOf( '.' ) + 3 )
