java.lang.Object org.apache.commons.nabla.algorithmic.forward.arithmetic.DRemTransformer2
public class DRemTransformer2
Differentiation transformer for DREM instructions.
This transformer is used when only the second argument
of DREM is an expanded differential pair. It is based on
the identity: a%b = a - q * b
where q is an
integer.
