The archive paper provides 10 example hard complex divions with answers. It also provides an algorith for measuring the accuracy of the result in "bits", which I have implemented. The robust cdiv algorithm is said to get 53 bits for all but #8 on the hard problems, where it gets 52 bits. I reproduce all of the results (also the default julia / reproduces results for smith's algorithm), except I get 0 bits on #5. I've tracked this down to the division of b/c returning zero inside robust_cdiv2, after r is also zero. But it's not clear how to fix it. | |

Pkg has noticed that your local git repository is not ready to create a pull request.
Best practice is to create a feature branch before you make any changes.
git checkout master
git checkout -b yourfeaturebranch
Then make your changes, including adding relevant test cases in to test/runtests.jl
, and ensure the tests all pass. Then commit our changes before running Pkg.submit("PackageName")
again.
git add .
