I have occasion to use roundd with the numbersystem=double,
unfortunately this seems to not work correctly.   All seems to be
okay in the default number system!

I have attached the test program  and show its output here.

default number system:
double number system

Is there any (easy) fix for this behavior?/

Many thanks in advance.
