Trigonometric Functions, Degrees and cas
Today I entered sin(22.5°) in cas-mode, angle-mode is radians, to check if it provides the intended solution, 1/2*sqrt(2-sqrt(2)). Instead it delivered: sin(22.5*°), using deg from convert didn't help either, sin(45/2) was not better. Clearly with sin(45*PI/360) it worked, so I think this is another bug in the Prime, interoperation between the cas and other parts of the OS is concerned.
