https://svn.boost.org/trac10/ticket/6030 <p> The documentation page for log1p mentions the alternative formula: </p> <blockquote> <p> log(1+x) == (log(1+x) * x) / ((1-x) - 1) </p> </blockquote> <p> This is apparently wrong. The correct formula is: </p> <blockquote> <p> log(1+x) == (log(1+x) * x) / ((1+x) - 1) </p> </blockquote> <p> (Note the sign of x in the denominator.) </p> en-us /htdocs/site/boost.png https://svn.boost.org/trac10/ticket/6030 Trac 1.4.3 John Maddock Wed, 21 Dec 2011 17:55:32 GMT https://svn.boost.org/trac10/ticket/6030#comment:1 https://svn.boost.org/trac10/ticket/6030#comment:1 <ul> <li><strong>status</strong> <span class="trac-field-old">new</span> → <span class="trac-field-new">closed</span> </li> <li><strong>resolution</strong> → <span class="trac-field-new">fixed</span> </li> </ul> <p> (In <a class="changeset" href="https://svn.boost.org/trac10/changeset/76098" title="Fix doc typo and regenerate.
