<p>The use of punctuation characters to separate subgroups in a number can make the number more readable. For instance consider 1,000,000,000 versus
1000000000. But when the grouping is irregular, such as 1,000,00,000; it indicates an error.</p>
<p>This rule raises an issue when underscores (<code>_</code>) are used to break a number into irregular subgroups.</p>
