This behavior is reproducible when you have "Fixed decimal" as the result format. On
any other format it works fine.

Indeed it happens only in that result format. Thanks for reporting, will have a look
as soon as I find the time.

The problem comes from float_round() which returns an (ignored) error and set the result
to NaN when the number to round contains too much digits (more than maxdigits). The
attached patch seems to do the trick (but the math lib is too hairy for me to understand
it fully, so maybe the patch breaks something).
