Hi João,
If you want precise control on the output, you might use the python
formatting (see
https://docs.python.org/2/library/string.html#formatstrings)
sage: x = RR(pi)
sage: print x
3.14159265358979
sage: print "{:.3}".format(x)
3.1
sage: print "{:.5}".format(x)
3.141
But perhaps it is not an answer to your question, is it?
