[LON-CAPA-admin] Perl Script Function "ln" supported?

The perl script function "ln" (not "log" or "log10") seems to be 
supported by LON-CAPA, but not officially. The Script Functions help 
doesn't list it and it's not a perl function.

The issue:
Some LON-CAPA servers do not support "ln" and complain "Undefined 
subroutine &main::ln ..." while others calculate the correct value.

So, why does it work on some servers? Should it work on all? If so, why 
isn't it currently?

Any hints?
