Hi Greg and Ken, thank you both for the very fast response. Is that behavior of NSScanner documented anywhere? I read the docs but don't remember coming across it. I'm a bit stunned. What's the point of having a scanner if it ignores certain key aspects of the locale?
NSNumberFormatter is the way to go then. Thanks again.
