Based on what I read from that link I tried:
r.mapcalc q50_eh_nonan = if(q50_eh != q50_eh,null(),q50_eh)
It assigned nan to 0. It would be great if r.null can use such a simple trick.

NaN is an abbreviation for Not a Number. Here is more info:
http://en.wikipedia.org/wiki/NaN
I was able to solve my problem by doing this: r.mapcalc q50_eh_nonan =
if(q50_eh != q50_eh,null(),q50_eh)

If by NaN you mean null values, you are looking for the r.null command

Hello All,
Is there a way to r.mapcalc or some other command to change NaN values in
rasters to another value?

If you mean real nan not grass NULL values, see this thread from the
grass-dev list from a few days ago:
