Two steps also, but Andrés Rodríguez’s solution should be still one byte shorter.

Andrés' solution looks unbeatable on size, but it is slower. Not a lot slower, to be honest, since it takes advantage of special cases in ACOS and SIN, so it really is quite brilliant. I wish I had thought of it.

CHS ISG X is flawed because the ISG skips the next instruction in the 0 → 1 case...
