     20    * Calculate the inverse cosine of a value.
     21    *
     22    * For matrices, the function is evaluated element wise.
     23    *
     24    * Syntax:
     25    *
     26    *    math.acos(x)
     27    *
     28    * Examples:
     29    *
     30    *    math.acos(0.5)           // returns number 1.0471975511965979
     31    *    math.acos(math.cos(1.5)) // returns number 1.5
     32    *
     33    *    math.acos(2)             // returns Complex 0 + 1.3169578969248166 i
     34    *
