Re: detect emulator
Try something like this...
Err err;
UInt32 value;
Boolean emulator;
err = FtrGet('pose', 0, value);
if (err) {
emulator = false;
} else {
emulator = true;
}

Re: Display a float on screen
Yup, look at the day-old thread titled [Q] Why is this difficult??? for yet-another-post of the FloatToString function. There is also this link http://www.duckpond.mv.com/Ftp/Pilot/fp.c to another solution.

Re: [Q] Why is this difficult???
Here's yet-another-version of the FloatToString function posted to this
group. It's not perfect (e.g. it does not handle large floats gracefully),
but it's a start. I don't know who's the original author, but many thanks
to him/her. I've added a fix (kludge?) to handle the case where rounding
propagates into the integral portion of the result. I also modified it so
that it returns a pointer to the internal buffer that holds the result,
rather than copying the result into a buffer provided as an arg. If you
find a better solution, please let us all know...

P.S. If you want more of the history ot this function, search the group
archive for FloatToString...
P.P.S. Insert standard disclaimer about how this code is provided as is,
with no claims of correctness implied, and how if you use it and your
unmanned spaced vehicle fails to go into orbit because of it, it's not my
problem, etc, etc, etc...

Of course this is the result from a computation and I would like to be
able
to print the results in a textfield.

Is it me? I am simply trying to print out in a textfield the number

and I can't seem to do it.
Can someone help?
