[rrd-users] Why with RRDs::update I do not have exactly the value in rrd db file?

[jvalenzu]

My perl script fragment:
                RRDs::update "$rrd/$filenamestring\_$gstring.rrd","-t",
                "$var1:$var2:$var3",
                "N:$val1:$val2:$val3";

The exact value of $val1, $val2, $val3:

4,4,4 respectively

My fetch data in the time:

Mon Sep  7 17:20:00 2009 4.0000000000e+00 3.9787671033e+00 3.9787671033e+00
Mon Sep  7 17:25:00 2009 nan nan nan

4 is not exactly equals to 3.9787671033e+00 I need to see exactly see 4.
Please let me know. Thanks.
