How to determine the max precision for double
<p>I am trying to determine what the maximum precision for a double is. In the comments for the accepted answer in this link <a href="https://stackoverflow.com/questions/322749/retain-precision-with-double-in-java">Retain precision with double in Java</a> @PeterLawrey states max precision in 15.</p>

<p>How do you determine this ?</p>
