Satellite position ID - need to know what western ones mean for my plugin - Englisch

Hello there,

For a plugin i am creating i wish to include a zap to channel feature, i have got the majority of it sorted but i am having some problems with codes for western satellites after i create instance of ScanSetup file.

the eastern satellites show like this (just the satellite degrees but without the . e.g. 192 instead of 19.2:

astra1 19.2east = 192
16.0east = 160
hotbird 13.0east = 130

However i have noticed the western ones have a different code, shown below is what i mean, i expected the western ones to be e.g. "-08" for 0.8west but it shows up as 3592 instead.

8.0west = 3520
5.0west = 3550
0.8west = 3592

Can somebody tell me how these codes are generated for western satellites and if indeed the eastern ones are simply the degree position without the dot? What can i do to the western ones to make them in a more readable format such as "-08" for 0.8west or will i just have to go around the western ones and work them out individually?

The code i refer to is the code within ScanSetup file, obviously the default satellite is 19.2, when i change "orbpos" to say -08 for 0.8west it just comes up as 61west instead.

cause it is a circle. all positions are related to 0° = south. e.g. astra is now 19,2° east of this position so it is 0192 but you can strip the leading "0". if your sat is on 5° west you look to the other side so you go the circle back but because it's a circle it is also 355° east and this means 3550 in this notation.

3600 comes from 360,0°

p.s.
btw Enigma1 has different counting way:
FFFF - 0.8 W = FFF8
FFFF - 4.0W = FFD8
...
