Methods

Modifier and Type	Method and Description
protected void	calculate() Simply calls MNumber.log(child).
protected void	calculateDouble() Simply calls Math.log(child).
OpNode	getDerivative(java.lang.String variable) Implements ln(f(x))' = f'(x)/f(x).
OpNode	getInverseOp(OpNode newChild) Returns the inverse function of this node.
RelNode	getMonotonicDecreasingRel(OpNode operand) Returns the relation that must be satisfied, so that this node with operand as child represents a monotonously falling operation
RelNode	getMonotonicIncreasingRel(OpNode operand) Returns the relation that must be satisfied, so that this node with operand as child represents a monotonously rising operation.
RelNode	getNodeDefinedRel(OpNode operand) Returns the relation subtree for which this operation with operand as child is defined.
RelNode	getZeroRel(OpNode operand) Returns the relation for which this operation with operand as child is zero.
java.lang.String	nodeToString() Returns the string representation for this node (without children).
