opnode http://www.openmath.org/cd/opnode 2003-04-01 experimental 2 0 This CD contains constructors for the operators used to describe the operations corresponding to operation nodes which occur in straight line programs. plus A constant value, constructs the plus for addition nodes. minus A constant value, constructs the minus for subtraction nodes. times A constant value, constructs the times for multiplication nodes. divide A constant value, constructs the divide for division nodes. return A unary function, takes a node of an slp, returns the value of the polynomial which corresponds to this node of the slp.
