Description edit

Returns the arccosine of expr in radians. In other words, if expr represents the cosine of some angle, then ACOS(expr) returns the angle. The returned angle will be in the range of 0 to π radians (which corresponds to 0 to 180 degrees). ACOS always returns a double-precision result.
