Calculation referring to additional python module not triggered about senaite.core HOT 3 CLOSED

Just noticed corresponding errors in plone setup:

NameError: name 'floor' is not defined
NameError: name 'poisson95_og' is not defined

It seems that the needed python libraries (e.g. math) are not imported correctly for the real calculations.

from senaite.core.

Another calculation fails, that contains strings and IF ... ELSE as part of the expression. It worked before and it still works in the calculation test view.
Might be a related to this issue...

from senaite.core.
