The exp node returns the exponential e to the power of the value of its child-node.

• Minimum number of child-nodes: 1
• Maximum number of child-nodes: 1
• Valid input range: no constraints, but results may under or overflow.

The exp node's value is calculated by raising e to the power of the value of its child-node.

value = e^x , where x is the value of the child-node
