Converting rationals, long double and integers

[edA-qa mort-ora-y]

I see a function "mpq_get_d", but is there also a function to convert to
a "long double"? I notice in the todo list a possible mpf_get_ld, but it
isn't available yet. Is there some other way I can convert a
rational/float to a long double without losing precision?

Is there a function to convert a rational directly to an integer with
truncating the fraction part? Is it enough to do "q.get_num() /
q.get_den()" ? In particular, will that always round towards zero?
