[NSNumber numberWithFloat:] issue

[Amr Aboelela]

Hello, 

I found that [NSNumber numberWithFloat:] is not toll free bridged with CoreFoundation

if you do CFRetain on an object result from [NSNumber numberWithFloat:] it will crash, and if you do a retainCount on it, it will always give you -1

I feel suspicious about this line:

return boxDouble(aValue, SMALL_FLOAT_MASK);
