If the numeric type is defined with precision=0 then it is treated as an 
integer.

I just did a test (in grass6.4.2 and grass7) with a table containing the 
following fields:

test_num numeric(10,3)
test_double double precision
test_num0 numeric(10,0)

test_num and test_double get imported as double precision, test_num0 
gets imported as integer.
