can we please change dtype to default to float64 !?
The default is float64 now (as long as you are not using numpy.oldnumeric).
I suppose more appropriately, we could reduce over float for integer data-types when calculating the mean as well (since a floating point is returned anyway).
Is now mean() always "reducing over" float64 ? The svn note """Log: Fix mean, std, and var methods so that they reduce over double data-type with integer inputs. """ makes it sound that a float32 input is stays float32 ? For mean calculation this might introduce large errors - I usually would require double-precision for *any* input type ... (don't know how to say this for complex types !? Are here real and imag treated separately / independently ?) Thanks, Sebastian Haase
