Set res to the value $\chi(n)$ of the Dirichlet character chi of the group G, respectively the values $\chi(0), \ldots, \chi(\mathit{len}-1)$ , as complex numbers. These are not methods: they are implemented for complex balls (acb) only and return GR_UNABLE otherwise. Declared only if dirichlet.h is included first.
