[GRASS5] Using fp

GRASS GRASS developer
1

I'm having some problems with the map operations because GRASS insists in truncating the cell values to integers.
I saw in some older documents that fp support would be integrated in GRASS5, but then I didn't find anything on how to use it (since most of the documents/tutorials refer to version 4.x).
Is this really implemented now? How can I convert my maps and/or make r.mapcalc operate with fp numbers?

Thanks,

Gualter

float (<expression>). If one of the input rasters is a float, the
output should stay floating point unless some integer operation is
performed "int (...)".
