Getting CG value

[Mikock]

Hi!

 

I have a small problem reading the current CG value from FSUIPC.

 

I always get very hight values.

 

For example: 4596416700483633152

 

And here is my source code:

[...]
long long int Value=0;
DWORD dwResult;
FSUIPC_Read(0x2EF8, 8, &Value, &dwResult);
!FSUIPC_Process(&dwResult);
return double(Value);
[...]

Maybe there is something wrong with my data type?

 

Thank you for your help in advance!

Hi,

 

I don't know much about C(++) but it looks like you've declared Value as a 64bit integer and then you're casting it to a 64bit Float (double).  This won't work because the cast just makes a new double with the same value as the integer; it doesn't change the data type of the variable (i.e. how the bits are interpreted).

 

You need to declare 'Value' as a double, then the bits returned from FSUIPC will be interpreted in the correct way.

It should be

double Variable = 0.0;

No need then for a cast. Why are you apparently putting this code into a function?

Thank you!

 

Now it works :)
