[ID 20000316.002] Math::BigInt and string ops
Message ID:
38D0BE71.19295.qmail@play.smurf.noris.de
This is a bug report for perl from smurf@noris.net,
generated with the help of perlbug 1.26 running under perl 5.006.


-----------------------------------------------------------------
[Please enter your report here]

$ perl -e 'use Math::BigInt;
           $foo = new Math::BigInt 12345;
           $foo =~ s/^\+//;
           print "$foo\n";
           $foo = int($foo/10+0.5);
           print "$foo\n"; '
+12345
NaN

*Sigh* Under 5.005, the above code was a legitimate method to convert
$foo to a normal string/number/whatever, thus the above code actually
printed

12345
1235

instead. Can we please reinstate the old behavior?

Incidentally, it seems that the ability to overload s/// would be rather
nice. The method would get the new value as input, and should return
either a new object which stringifies to that value, or the original
string, which is then assigned to the left-hand side of the =~.
