Re: Regrid vegetation's type data

Guangshan,

There's no way to tell f2gsh to return integers.

You can use one of our truncation functions, but you may lose
information.

For example, you can call "floattointeger" on the output:

   X = floattointeger(f2gsh (x, (/jlat,ilon/), 42))

There are also functions "round", "ceil" and "floor" which do
different kinds of truncation/rounding. "ceil" and "float" return
floats, but they are whole numbers.
