Close #12541

Hi @mattcrewe, thanks for the PR.
np.angle computes the angle of a complex input, so I am not entirely sure of the reasoning behind the TODO you added. Could you please elaborate on this?
Otherwise, lgtm.

Hi @MuhammadSaeedBatikh.
While the angle function is intended to take complex numbers as input the np.angle function will accept integer and float numbers as input; the other backends also mirror this behaviour. I am currently not testing for cases outside complex numbers as the current frontend implementation is only suitable to handle complex inputs. I left it at this point as it matches the current solutions for the other backends.

Makes sense. But no need to worry about that as these dtype conversions (if supported) are handled by the backend functions anyway. I'm just gonna remove the comments/TODOs and merge the PR. Thanks.

Hello @mattcrewe and @MuhammadSaeedBatikh, I happened to spend some time working on this function because it was not marked 'completed' here: #1525. Later while going through the codebase, I realised that the code for angle() has already been pushed. Please do the needful. Thank you.
