Thanks Achim, I'll think about that one...
I guess the main thing that's confusing to me, is it seems that according to
NSNumberFormatter, the default behavior seemingly should be that things should
be a float. So, I'm not 100% sure why this is happening, or anything would need
to be done to enable the formatter to create floating point.
For instance:
[formatter setAllowsFloats:YES];
Could be called, where formatter is an NSNumberFormatter, but the default is
supposed to be that this is true anyway.
I also tried:
[formatter setGeneratesDecimalNumbers:YES];
Which is also supposed to be true by default. And I tried a few permutations of
this.
I haven't really gone through the example code with a fine tooth comb yet, but
it would be cool to get it working, because other than that "it works for me".
I half suspect that the formatter behavior for the qcindexport, where
allowsFloats is turned to false, may be affecting the behavior of the number
ports later. (I should also test this and compile before sending back to list,
but hey, someone may have already been through this one before.)
