Test whether x is a whole number

• is_wholenumber() uses base::round() to test whether x is a whole number, it will therefore issue an error if x is not of mode numeric. If used in base::stopifnot() for example, this won't be a problem but it may be in conditionals.

• is_scalar_wholenumber() comes with the additional argument check_numeric to check whether x is a numeric before checking it is a whole number.

Usage

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

is_scalar_wholenumber(x, check_numeric = TRUE, ...)

Arguments

x

Object to be tested

tol

Tolerance
