Thanks for the information. I have tried to do an exact conversion but
it seems that this cannot be done. In particular, I don't seem to be
able to convert the MP_Float type to the respective CORE type without
going over the double type.
I also tried to use the circular Kernel based on the CORE::Expr number
type but that proved to be much too slow.
