Lat and Long

[PhoenixRET]

What is the proper expression for converting the Lat and Long data after you extract it from FSUIPC ?

Thanks In Advance

I explain it in words in the SDK programmers guide -- the recently elaborated explanation should surely be clear enough? I don't give expressions as how to do it would be different in each language.

Thanks Jose, I am writting in Basic.net but I am sure I can convert the code. Thanks Again....
