String to Integer?

Seriously, I'm asking you how to get an Integer from a String.

I've tried Integer#readFrom: which does not work, probably because it expects a Stream.

After browsing through Integer and String I still have no idea how to convert a String into an Integer.

Help?

Regards,

Markus Kahl

Or to make sure you only read the string to the first non-Integer
character:
Integer readFrom: '300017.9' readStream
=> 300017

Or that you end up with an Integer:
'300017.9' asNumber rounded
=> 300018

Since much behavior is inherited, it is often useful to include some superclasses in your browsing. I often right-click in the method pane of the browser and select a superclass in the 'Visibility' submenu. For example, when brosing Integer, choosing 'Visibility' -> Object would have shown me the #readFromString: class method. While browsing String, 'Visibility' -> CharacterArray would have sufficed to find the instance method #asNumber.
