cos(1) returns 0.54030
My calculator Casio fx-100D returns cos(1) as 0.999847695.

Using Octave 4.0.0/Win8.1.

I am not sure whether to post this as a bug to, as I still have not identified the mathematical roots of cosine.

Casio Headquarters are in Shibuqa, Tokyo Japan.

Thanks and regards,

If you would have read the f* manual after you encountered the problem, it would have been clear:

that the function cos expects as input radians. If you don't know what radian is, please consult an
appropriate textbook of your choice.
Good luck
