[SciPy-dev] numpy.float64*poly1d = array
Wed Sep 5 21:52:43 CDT 2007
I filed a ticket for this and I guess it is technically a numpy
problem, but I am curious about it. One line recreates the problem
array([ 10., -10.])
I went in and added a little debugging print statement to the __mul__
and __rmul__ methods of poly1d, and neither is called when the
numpy.float64 instance is on the left.
calls __mul__ and works fine.
calls __rmul__ and works fine.
I got myself in this situation by multiplying a poly1d by a constant
taken from an array, which is a numpy.float64 instance.
This seems to indicate that
is handled entirely by the float64 __mul__ method without calling
__rmul__ of poly1d. Does that seem possible? I think that is what is
happening because my cheesy
print('in rmul') statement isn't triggered.
