Stan,

see exactly what I expected, he is actually loosing significant
data by doing what he does ... so maybe rrdtool  shouldcomplain
realy loud and only enable float processing if called with a
sepcial option

--yes-this-is-realy-float-data-and-not-me-doing-things-I-should-not-do-because-I-am-going-to-lose-significant-data-at-the-low-end
