[PD] how to change symbol to float

[Richard Millig]

hi all,

i hope this could a be a simple issue for someone:
i'm getting following from [unpackOSC] after changing values of a 
vslider in AndrOSC:

/vslider 0\\,123

and
[pipelist]
|
[routeOSC \vslider]
|
[print] prints then: 0,123

so how to change this symbol in a float like 0.123?
or does somebody know how to fix this in AndrOSC?

greetings and thanks for helping
richard
