<p>
The <a href="/pkg/strconv/#NumError"><code>NumError</code></a>
type now has
an <a href="/pkg/strconv/#NumError.Unwrap"><code>Unwrap</code></a>
method that may be used to retrieve the reason that a conversion
failed.
This supports using <code>NumError</code> values
with <a href="/pkg/errors/#Is"><code>errors.Is</code></a> to see
if the underlying error
is <a href="/pkg/strconv/#pkg-variables"><code>strconv.ErrRange</code></a>
or <a href="/pkg/strconv/#pkg-variables"><code>strconv.ErrSyntax</code></a>.
