[ferret_users] write missing value into output netcdf



Hello,

I have a little trouble when I try to write missing values (2**100) into an output netcdf file. For example,

yes? use old.nc
yes? show data
name title I J K L var1 1:2000 1:1000 ... ...
yes? let largenum=2^100
yes? list/precision=7 largenum
       1.267651E+30
yes? set variable/bad=largenum var1      (this attempt failed)
yes? set variable/bad=2^100 var1 (this attempt passes but the missing value is 2 not 2^100)
yes? save/file=new.nc var1

Any trick here? I can directly set variable/bad to 1.267651E+30 but again that's not exactly equal to 2^100.
Thanks,
Haoping
