New Revision: 5056

Modified:
   trunk/numpy/ma/core.py
   trunk/numpy/ma/mrecords.py
   trunk/numpy/ma/tests/test_core.py
Log:
mrecords: clean-up
core: MaskedArray.__setitem__ : when hardmask is False, force the data to be updated before the mask.
core: MaskedArray.round_ : fixed to keep the dates on TimeSeries
core: round : simplified
