[hobbit] hobbit not adding negative values to rrd database

If I recall correctly, I believe rrd/do_temperature.c assumes all numbers are positive integers. Negative numbers and floating-point numbers will confuse it enough to fail to parse the input properly.

Hi I have a temperature monitor for outside temperature.

i cant get it to work when the temperature is negative.

the rrdtool reports this <rrd> <version> 0003 </version> <step> 300 </step> <!-- Seconds --> <lastupdate> 1170011401 </lastupdate> <!-- 2007-01-28 20:10:01 CET -->

            <min> -4.0000000000e+01 </min>
            <max> NaN </max>

            <!-- PDP Status -->

            <value> 4.0000000000e+00 </value>
            <unknown_sec> 0 </unknown_sec>
    </ds>

if i send positive values it gets updated but when it is negative nothing happens.

any ideas?
