as @m{\pi,Pi}, either because the user has called a function like
@code{mpfr_const_pi} directly or because such a function was called
internally by the MPFR library itself to compute some other function.
+When more precision is needed, the value is automatically recomputed;

At any time, the user can free the various caches with
@code{mpfr_free_cache}. It is strongly advised to do that before
