fsuipcclient.dll [FS9][FSUIPC3.999] Fuel weight

[ztajti]

Hi!

I try read the 0x0AF4 offset (Fuel weight as pounds per gallon; size: 2) and the simulator write, the fuel weight is 6.7 Lbs/Gal, the Client read in 6 Lbs/Gal.

It's my code:
 

Offset<double> fuelWeight = new Offset<double>("fuel", 0x0AF4);

How I can read the real weight value in double/float/decimal?

The double result is
 

Which type should I use to work in correctly?

Thank you!

It's not "pounds per gallon", but  punds per gallon * 256. The * means "multiplied by". If you are getting 6 you are ignoring the fraction! 6.7 would be 1715.

It's a  2 byte integer, so a 16-bit value. in C is would be a "short", or in Windows terminology, a "WORD".

After you read it, if you want it as a floating point value, divide it by 256.0.

Please do read the details in the offsets list more carefully. Where they are floating point they are explicitly listed as such -- as "double" (64-bit = 8 bytes), or "float" (32-bits = 4 bytes).
