    dct:description "The library multicomplex is an implementation of multicomplex algebra in C++ to allow for higher-order derivatives of numerical functions.  Many (though not all) mathematical functions are implemented, allowing for calculation of derivatives (straight and mixed) to approximately numerical precision, which is difficult or impossible to achieve in conventional double precision" ;
