Hi all:

 

I am using the precipitation (pr) data from rcm3-cgcm3 model. I used the
ncdf4 package to open the precipitation data. Some values are very close to
zero, for example 3*10^(-23),  and there are even some negative values (like
-3*10^(-21)). Should I treat these values as zero? I don't know whether this
problem is caused by the R.  Anybody knows what cutoff should I choose for
the float point data? 

 

Thanks
