Description

Currently magnitude of complex is returned by calling abs while phase angle is returned by calling getArgument(). I propose deprecating getArgument and using arg() because:

– it's not really an accessor method since the argument is computed
– arg() is shorter, more elegant and similar to abs() with which its usage will sometimes be paired
