“coercing” them to a common parent and performing arithmetic on theĬoerced elements. When doing arithmetic with two elements having different parents, When writing Cython code, _add_ should be a cpdef method: If the implementation is generic across all elements in a givenĬategory \(C\), then this method can be put in C.ElementMethods. Within _add_(self, other), you may assume that self and To implement addition for any Element subclass, override theĭef _add_(self, other) method instead of the usual Python We describe here the rules that mustīe followed by both arithmetic implementers and callers. Manage uniformly mixed arithmetic operations using the coercion model. Sage has a special system for handling arithmetic operations on SageĮlements (that is instances of Element), in particular to That creates a new sibling very quickly from defining data _new_ ( FreeModuleElement_generic_dense ) x.
