is_bare_integerish

is_scalar_integerish

These predicates check whether R considers a number vector to be
integer-like, according to its own tolerance check (which is in
fact delegated to the C library). This function is not adapted to
data analysis, see the help for <code><a href="/link/base%3A%3Ais.integer()?package=rlang&version=1.1.3" data-mini-rdoc="rlang::base::is.integer()">base::is.integer()</a></code> for examples
of how to check for whole numbers.
Things to consider when checking for integer-like doubles:<ul>
<li>This check can be expensive because the whole double vector has
to be traversed and checked.</li>
<li>Large double values may be integerish but may still not be
coercible to integer. This is because integers in R only support
values up to <code>2^31 - 1</code> while numbers stored as double can be
much larger.</li>
</ul>

A toolbox for working with base types, core R features
like the condition system, and core 'Tidyverse' features like tidy
evaluation.
