doc floor
doc ceil
doc round
What happens if you use one of these functions and compare the result to the original value?

If n is your number, then
round(n)==n
is true if and only if n is an integer

Use the rem (link) or mod (linked to in that page) functions.
isint = @(x) rem(x,1) == 0;
It returns a logical result.
