It may sound easy, but i don't figure out how it works.
I want to export a floating point variable I produced in IDL to use it
in a GIS. Everything I export through the iTools ends in integers, but
I need to keep the original float values!
who can help me?

exactly, thanks a lot!

It seems you may be looking for the float (or double) keyword to
write_tiff.

I want to make a floating point file i can use in a GIS, preferably a
Tiff.
Let's say I have some Tiffs with NDVI values (0-1). I import them in
IDL, make some calculations, and get a new variable I want to export
to my GIS. But I need floating point grids.
Or another example: I import a variable of a ncdf with floating point
values. I shift it, and want to export it so I can use it in the GIS..

You need to say more about what kind of file you want to make.
