Check if the value returned is equal to the value returned casted to an int?

to check if x is an integer, round(x) must equal to x.

why not just
code:
if (i%2 == 0) // if is 0 then there is no remainder (decimal), or else is 1
Integer is a reference type, you cannot compare a int (data type); (i/2), with a reference type; Integer.
