Check for whole number values

Unlike is.integer(), which checks the type of argument is integer, this function checks whether the value of the argument is an integer (within a specified tolerance).

Usage

is.wholenumber(x, tol = .Machine$double.eps^0.5)

Arguments

x

a vector

tol

a numeric tolerance

Value

a logical vector indicating whether x has a whole number value

Details

This function is borrowed from the examples for is.integer()

Examples

is.wholenumber(1)
#> [1] TRUE
all(is.wholenumber(rbinom(100,10,.5)))
#> [1] TRUE
is.wholenumber((1:10)/2)
#>  [1] FALSE  TRUE FALSE  TRUE FALSE  TRUE FALSE  TRUE FALSE  TRUE
