Actually, Robert makes a good point.  arange with floats is 
problematic.   We should direct people to linspace instead of changing 
the default of arange.  Most new users will probably expect arange to 
return a type similar to Python's range which is int.

Also:  Keeping arange as ints reduces the number of errors from the 
change in the unit tests to

2 in NumPy
3 in SciPy

So, I think from both a pragmatic and idealized situtation, arange 
should stay with the default of ints.   People who want arange to return 
floats should be directed to linspace.
