The acos node returns the arc cosine of the value of its child-node.


  • Minimum number of child-nodes: 1
  • Maximum number of child-nodes: 1
  • Valid input range: -1. to +1.
  • Output range: 0 to _pi_ (radians)


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 value1:

value = cos-1(value1)

For invalid value1:

value = ERROR
