is.wholenumber(x, tolerance = sqrt(.Machine$double.eps))

as.wholenumber(x, ...)

`x`	a vector to be tested.
`tolerance`	numeric. Differences smaller than tolerance are considered as equal. The default value is close to `1.5e-8`.
`...`	Additional arguments passed to or from other methods.

A logical, TRUE if all values of x are (finite) whole numbers. If x contains NA or NaN, then NA is returned.

x = c(1L, 10L)
is.integer(x)
is.wholenumber(x)

x = c(1, 10)
is.integer(x)
is.wholenumber(x) # here is the difference with 'is.integer'

is.wholenumber(1+10^(-7))
is.wholenumber(1+10^(-8))
