is_wholenumber: Test if the values of a vector are whole numbers

In paulponcet/bazar: Miscellaneous Basic Functions

Description

The function is_wholenumber tests if values of the numeric vector x are all whole numbers (up to a tolerance).

The function as_wholenumber is a synonym for as.integer.

Usage

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

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

as_wholenumber(x, ...)

as.wholenumber(x, ...)

Arguments

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.

Value

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

Examples

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))
