I think you are looking for

Note that this one tests if 'a' can be stored accurately as a 32-bit signed

e.g. is.wholenumber(1)

You should say what was unsatisfactory about the answer you were offered:
http://stackoverflow.com/questions/26434652/data-smooth
It sounds like you want an 'is.integral' function to tell if a
number acts like a mathematical integer, as opposed to
'is.integer', which tells if a number is stored as a 32-bit
computer integer. The test will depend on what properties
of mathematical integers you are most interested in.

It's due to that, 1 is a numeric, 1.2 is a numeric, though it's true. but
deeply, when i want to know 1 is an integer, there seems no easy way to get
the answer.
So, is there anyone happen to know it?

If you do floating point arithmetic on integers you'll usually get floating
point answers, including the 5.0.
See FAQ 7.31 for the usual floating point problem, and ?all.equal for the usual
answer to it. You could see if a result is cl

is.integer is surely what you need if
Dear usRers,
I want to judge virable is or not a integer?
e.g. is.integer(1) FALSE because it is a numeric, but i want it's true.
as.integer may not be used. because i don't know a is 1 or 1.1.
