Been testing output the mag heading with the "Current heading" in the selection in mobi. And it works 0-180 degrees, after that it starts to act strange, showing -18-17 etc.

I looked at the transform and it looks right to the fsuipc values.

0580 4 Heading, *360/(65536*65536) for degrees TRUE.[Can be set in slew or pause states]

In other Words.
In Transform it should be like $*360/(65536*65536) and that becomes $*8,381903171539307e-8 and if shorten its like $*8.3819E-08

Issue.
It displays the current heading correct (ish) between 0-180, the it goes zoombie.

Any ideas?

Try

Transform: $*0.00000008381903171539306640625

That's what you have done already

The go to the COMPARE-Tab:

set the following values

if actual value is < 0 - where < is the first value and 0 the 2nd
then insert in the next field after then set $+360
and in the 3rd field type only $

This should solve your problem.

Hi Japmaco.

Please my friend use search engine if posible. This is explaned already in some topics !
For example here .... https://www.mobiflight.com/forum/message/4321.html

In short words....

The Transform is correct. We normaly use not a full math formula.... we calculate the steps and use a final multiplication. This is a relict from the first days of Mobiflight.... There it was not a transform field like today where you can use the full Expressions..... This time you only could make ONE Multiplication. So you have to shorten the hole calculation to ONE Multiplicator.

Your Problem:
Stephan gives already the correct solution.

Just for information. This is a Signed/Unsigned Problem.
Every offset can have 2 Conditions.... Signed or Unsigned. this means its range is Only Positiv or it is split in 50% Positiv and 50% Negativ.
In Most situations this is not a problem..... But some Offsets are not use the Mobiflight Standard System.... In that cases you have to work with a "IF less then Zero, then $+ xxxxx" Technic.
(For example in the AP Altitude of PMDG) .... Again please use Search Engine.

Have Fun !
