I tried calculating the roots with logarithms, but the problem with that is that the built-in log() function is only accurate to a fixed number of places. Other than the logarithm method and Newton's method, I don't know of any other ways to calculate roots. Does anyone know how to calculate a logarithm manually? That is, calculate a logarithm without using the built-in log() function?

My C and C++ skills are virtually non-existent, so sadly, that option isn't really available to me. This might be a good time to improve those skill, eh? ;-)

• Are you posting in the right place? Check out Where do I post X? to know for sure.
• Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:

  <code> <a> <b> <big> <blockquote> <br /> <dd> <dl> <dt> <em> <font> <h1> <h2> <h3> <h4> <h5> <h6> <hr /> <i> <li> <nbsp> <ol> <p> <small> <strike> <strong> <sub> <sup> <table> <td> <th> <tr> <tt> <u> <ul>

• Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
• Want more info? How to link or How to display code and escape characters are good places to start.
