You beat me to it by a few minutes, while I was trying to log in !

I noticed too that the displayed number is Sqrt(5) = 2.236067977499... so if the number was calculated (instead of simply keyed-in) then it was truncated to ...49 instead of rounded to ...50, as would be expected.

Anyway, perhaps the OP has detected something else in the picture ...
