[rrd-users] How to get decimal output from rrdtool fetch?

[demeo]

At beginning sorry for my level of English. 

I want to ask about possibility to get decimal output from rrdtool fetch
command. 
Now when I make for example: 
rrdtool fetch temp_serw1m.rrd AVERAGE --start -60 
I get: 
1228690200: 2.2100000000e+01 

but I want to have 22.1 as output to have possibility process this data in
other programs/scripts. 

Thanks for any answer.
