No.

Other

Any other information relevant to this pull request? This may include screenshots, references, and/or implementation notes.

The Julia implementation of cosc(x) went bananas for approximately every tenth value of x in the tiny negative and tiny positive test range To make the tests pass I decided to just skip these fixture values (often in the range of 1e+300 when in fact they should be ~0).
