I had a vector of size (1 x 65536). How can i check whether all the elements in that vector is an integer.

There some values are stored as 8.8744e+05 while checking the workspace. Is that a problem for doing bitxor operation. Those values are also considered as integers, right?

check = [1 1.5];
logical(~rem(check,1))

Ran in:
This produces a logical array indicating whether each element is an integer. If you want to check whether all the elements in an array are integers, then I would suggest a slight edit:
check = [1 1.5];
sum(rem(check,1))==0 % check that there are no non-integers
ans = logical
0
check = [1 1];
sum(rem(check,1))==0 % check that there are no non-integers
ans = logical
1
