can't enter a num. in xl cell, which is more than 16 digit or lon

[SUbodh Jain]

you can't enter a numeric no which is more than 16 digit or longer,the last
digit automatically turns to zero.


Try entering 1234567891011121

you will see that the last digit 1 turns to zero. if you put the number in
text format then it will accept the same.
