+====== Description ======
+The acos node returns the arc cosine of the value of its child-node.
+====== Constraints ======
+  * Minimum number of child-nodes: 1
+  * Maximum number of child-nodes: 1
+  * Valid input range: -1. to +1.
+  * Output range: 0 to <m>pi</m> (radians)
+====== Calculus ======
+The acos node's value is the arc cosine, in radians, of the value of its child-node. If the input value is out of range then the acos node returns an ERROR value.
+For valid value<sub>1</sub>:
+value = cos<sup>-1</sup>(value<sub>1</sub>)
+For invalid value<sub>1</sub>:
+value = ERROR
