<overview>
<p>
Integer literals starting with the digit <code>0</code> may be interpreted as octal numbers by some platforms
but not others, and thus should be avoided. This does not make a difference for the literal <code>0</code>
itself.
</p>

</overview>
<recommendation>

<p>
If the literal was meant to be octal, convert it to a decimal or hexadecimal number. Otherwise, remove
the leading zero.
</p>

<example>

<p>
The following example uses the literal <code>012</code>, which some platforms will interpret as an octal
encoding of the decimal number <code>10</code>, while others will interpret it as the decimal number
<code>12</code>. Depending on the desired interpretation, it should be replaced with either <code>10</code>
or <code>12</code>.
