ERROR: not a simple signed integer: '110817.534'

Hello!

I'm getting this error:

ERROR: localhost.localdomain-if_wlp1s0-down-d.rrd.new: not a simple signed integer: '110817.534'

While running 'rrdcopy' script. With which issue following command:

rrdtool update localhost.localdomain-if_wlp1s0-down-d.rrd.new --template 42 1693920600:349626.962138889 1693920900:349626.962138889 1693921200:349626.962138889 1693921500:349626.962138889 1693921800:349626.962138889 1693922100:349626.962138889

The file "localhost.localdomain-if_wlp1s0-down-d.rrd" is a simple rrd with ds[42].type="DERIVE"

It is a bug?

Dumping this file showing a lot of floats, so I expect 'rrdtool update' will properly insert floats. But it complains.

rrdtool dump localhost.localdomain-if_wlp1s0-down-d.rrd |grep row|tail -3
