Hi,

I am having a bit trouble with the MCP and speed settings.
My entire flight deck works perfectly and so does the autopilot with overspeed, underspeed etc. BUT there is a problem with the MACH reading.
Have noticed that the FSUIPC output sometimes to specific vales, many of them above .73 is not the exact number, the output value can be 0.74999999999999 and that sjould be 0.75. In this case the instrument does not show 0.75 it shows a strange value instead, something not even like the figure that FSUIPC gets as an output.

How to solve this?
The FSUIPC is not the perfect output source since they have forgot to program specific settings for this output. Is it possible to find a solution for this and to program either Mobiflight so it becomes correct or reprogram FSUIPC software?

The easiest way to solve this problem please.
Thank you and hopefully you have a good simulator time as am I at this point.

Hi sebpil,

try a formular into the transform line:

round($*100,0)/100

If $=0.749999 then you multiply it by 100 and you will get after the round function 75 and zero digits after the decimal. Divide this through 100. The result is .75.

Hello

Problem is solved. Can only blame myself for the problem.
Made a wrong setting in Mobiflight on Compare section.
I wrote like this:
Round($/10.0)
and when doing so it was not possible to run mobiflight. First of all I just had this line: ($/10.0), and then it worked to run Mobiflight but with error.
Now I corrected it to:
Round($/10,0)

And now everything works great!
It stead of a decimal point I had set period and that was the entire problem.

Thank you for your support. Now I am very happy again!

Hi

Please remember this information for the future, too.

In the Mobiflight expressions Syntax ( That is used for everything like Transform, Compare, Precondition and so on ) there is a big difference between decimal ,,,,,, and point .....

In a Float Value there is used a POINT like 12.5 1.234 and so on. The DECIMAL itself is a part of the code. It split parameters for example.
A "IF ELSE" function for example looks like if($=1,100,200) Here the DECIMAL splits between IF,THEN,ELSE.
In the Round function it splits between Value,Diggits like Round($,1)

Also important.... A Command must be write corect.... "round" will not work. It must be "Round"
