[rrd-users] CDEF,RPN, no decimal constant possible?

I get the same issue on a raspberry pi with Debian Wheezy and locale
and RRDtool 1.4.7      Compiled Sep  4 2012 23:43:06

Create rrd:
rrdtool create L.rrd  --step 1 DS:DeLog_L:GAUGE:2:U:U
DS:L:COMPUTE:DeLog_L,LOG,4.342944,* RRA:AVERAGE:0.5:1:10

Get Info:
rrdtool info L.rrd
ds[L].cdef = "DeLog_L,LOG,4,*"
Do some updates with
rrdtool update L.rrd N:1000

And a dump show not the correct result of 30:
rrdtool dump  L.rrd

rrd_info show that is a problem in rrd_create, which convert the input
string "4.342944" to the number 4 in the rrd.

So I assume all  compilations - linux and  windows - are affected.
