$0570 erro result

[Mário Grossi]

I'm using Delphi2007 to get altitude with $ 0570 using (* 3.28084 / (65536 * 65536)). But the result is a huge number with 8 digits.

please, help

my code

 

var
  altitude: comp;
begin 
  if FSUIPC_read($570, 8, @altitude, dwResult) then
  if FSUIPC_Process(dwResult) then
   altitude :=  altitude * 3.28084/(65536.0*65536.0);
  altitude := round(altitude);
end;

What actual value of altitude does  that expression give when it is executed?

 

Read the description of $0570 - it isn't what you think it is.

 

altitude := altitude * 3.28084/(65536.0*65536.0);
