*ACOS() returns the arccosine of a number
==Description==
* The value of ACOS(Number) in radians in the range 0 to pi().
* The value of ACOS(Number) in radians in the range 0 to pi().
*Calci returns the value of arccosine (inverse cosine) in Radians.
*Calci returns the value of arccosine (inverse cosine) in Radians.
*The number can be a single value or any number of values.
*The number can be a single value or any number of values.
For example, ACOS(0.5,(-0.2),1) gives the arcCOS or inverseCOS values for each element.
