I wanted to create "bignum usability" SOPW question, but then the SS landed me right here, -- very fresh thread. This pragma is in the core, but how usable/advised/maintained it is?

use strict; use warnings; use feature 'say'; use bignum; # (1) #use bignum downgrade => "Math::BigInt", upgrade => "Math::BigI +nt"; ## (2) #use bigint; say $^V; say my $x = 21778071482940061661655974875633165533182; say my $y = $x / 2;


v5.38.0 21778071482940061661655974875633165533182 10889035741470030830827987437816582766590

off-by-one error. Using commented-out lines instead gives me (1):

Deep recursion on subroutine "Math::BigInt::bdiv" at C:/berrybrew/stra +wberry-perl- line 2229

and the Perl process hangs, or (2):

21778071482940061661655974875633165533182 10889035741470030830827987437816582766591

i.e. "don't use bignum if bigint suffices" will produce the correct answer, but doesn't smell quite right

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.
