Numpy requires the error to be less than the sum of the relative and absolute errors, the pep uses the maximum of the two. The other is that numpy as a key word for nans to compare equal.

But not enough that it makes sense to change the numpy one. The results will be similar in most cases, and identical fir a relative tolerance less than 1e-8 (for float64). -Chris > -n > > -- > Nathaniel J.

Indeed, congratulations Chris! Are there plans to write a vectorized version for NumPy? :) On Mon, Mar 2, 2015 at 2:28 PM, Nathaniel Smith wrote: > ...on the acceptance of his PEP!
