[mrtg] Decimals from monitoring script

I am trying to monitor a special temperature device with help of MRTG. I 
have programmed my own little script which perform this, but MRTG doesn't 
accept the values that are given from my script.

My script reports the temperature with one decimal like "0.3". I have made 
a workaround with negative numbers, so that is allready fixed.

Can I in some way get MRTG to be nice to numbers with one decimal or do I 
need to do some kind of multiplication in my script (like X * 10) too fool 
MRTG and then divide the result with some config parameter (like X / 10) in 
mrtg.cfg so I get the correct result in my graph in the end. But it seems 
like it isn't possible to divide in MRTG...just do multiplication...

Thanks for your help
