Can I work on this issue?

[certik]

@ShikharJ of course! You can work on any issue you want. Let us know if you need any help.

@certik I have made the changes as specified, though I am clueless about running the tests (that the development workflow page recommends to run). How can I run the tests, and finally add the modified files?

[isuruf]

Run ctest from the build directory. (ctest -v for more verbosity)

[ShikharJ]

It returns No Tests Were Found!!!. Please help.

[isuruf]

@ShikharJ, are you running it from the directory that you built symengine? Can you post the commands you used when building symengine?

[ShikharJ]

I see my mistake. Thanks @isuruf !

[ShikharJ]

@isuruf @certik I've run cmake ., make and ctest. They all run fine. What should I do next?
