( [id://3333]=superdoc: print w/replies, xml ) Need Help??
After adding to Math::Int128 a new set of operators that use a preallocated argument for output, Math::Int128 becomes faster than Math::GMPz, around 60% faster

That's more like the figures I anticipated (at a guess).
My "I don't see much scope for improvement" comment was in relation to my own enhancements to Math::Int128 which removed the allocating/deallocating you mentioned - and which made the int128 multiplication a little faster than using Math::GMPz's functions (and, of course, significantly faster than using Math::GMPz's overloaded operators).

When I get back to my Vista64 box, I'll grab the latest github version and see for myself ... and, of course, post again with my results for that machine.

Cheers,
Rob

Title:
Use:  <p> text here (a paragraph) </p>
and:  <code> code here </code>
to format your post; it's "PerlMonks-approved HTML":



  • 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.
