<p>Special operations are available to mitigate this problem with numbers
rounding when they get close to one. For example, consider the
operation <code>log(1 + x)</code> for positive <code>x</code>. When <code>x</code> is small (less than

argument will round to 1 and the result will round to zero. To allow
more granularity, programming languages provide a library fu
