Closes #340

[x] I have updated CHANGELOG.md
[x] I have added tests to demonstrate the contribution is correctly implemented: this usually includes both positive and negative tests, showing the happy path(s) and featuring intentionally broken cases
[x] I have run all the tests locally and no test failure was reported
[x] I did not do unrelated and/or undiscussed refactorings

@anton-trunov I've also decided to add error-throwing into log2 function for case with num = 0, because TVM doesn't throw in this case.
