 <p>Note that R won’t save a number as an integer unless you include the <code>L</code>. Integer numbers without the <code>L</code> will be saved as doubles. The only difference between <code>4</code> and <code>4L</code> is how R saves the number in your computer’s memory. Integers are defined more precisely in your computer’s memory than doubles (unless the integer is <em>very</em> large or small).</p>
-<p>Why would you save your data as an integer instead of a double? Sometimes a difference in precision can have surprising effects. Your computer allocates 64 bits of memory to store each double in an R program. This allows a lot of precision, but some numbers cannot be expressed exactly in 64 bits, the equivalent of a sequence of 64 ones and zeroes. For example, the number latexmath:<span class="math inline">\(\pi\)</span> contains an endless sequences of digits to the right of the decimal place. Your computer must round <span class="math inline">\(\pi\)</span> to something close to, but not exactly equal to <span class="math inline">\(\pi\)</span> to store <span class="math inline">\(\pi\)</span> in its memory. Many decimal numbers share a similar fate.</p>

 <p>As a result, each double is accurate to about 16 significant digits. This introduces a little bit of error. In most cases, this rounding error will go unnoticed. However, in some situations, the rounding error can cause surprising results. For example, you may expect the result of the expression below to be zero, but it is not:</p>
