plus sign before cell reference in formula

[KrispyData]

what is the difference between this formula:

=+C31*$D$14

and this one:

=C31*$D$14

both formula give the same results. what is the purpose of the plus sign?

 

[Bernard Liengme]

The plus sign serves no useful purpose whatsoever
It does tell us that maybe the originator of the workbook began life as a
Lotus 123 users where formulas began with +. And that they have not yet
found that Excel does not require them (old habits die hard - or not at all)
