Re: Converting doubles to strings

CFNumberFormatterGetValueFromString...examine the CFRange* parameter after the call to see how much of the string it used.

This works pretty well for my text filtering task. But I do find something wrong with the range passed to CFNumberFormatterGetValueFromString. That is if the location is not 0, meaning start from the beginning, it still parse the string from the beginning. This makes converting a long string with several numbers in it impossible.

Does anyone else see this too?

Yes, I can reproduce the problem, with some initial difficulty. I was able to reproduce the problem by using CFStringCreateWithCharactersNoCopy, but not when I used CFStringCreateWithCharacters.

You can work around this by using CFStringCreateWithSubstring when you need to work with part of the string that doesn't start at the beginning.
