I can reproduce this with Math::BigInt v1.73, but not with v1.74 (which I intent to release shortly). (It seems your script dies at the "blcm" call, and the reason is because you pass it BigFloats, and __lcm() could not handle this, nor forward them to BigFloat (because blcm() was borken in BigFloat since basically ever - even MBI v1.28 or so has the same borkened version). I noticed the non-working bgcm() and blcm() calls a few days ago, fixed it today, fixed something in BigInt related to __lcm(), and only then dug out your report and found it was also fixed :o) :~/perl/math/Math-BigInt-1.73> perl -Ilib core.pl Can't use an undefined value as an ARRAY reference at lib/Math/BigInt/Calc.pm line 980. :~/perl/math/Math-BigInt-1.74> perl -Ilib core.pl 0.02955321367635349698196488311203224657733277925009198076731622388624965866492863628736572899380612750478561 0.029553213676353496981964883112032246577332779250091981 Can you please retry this with v1.74 from: http://bloodgate.com/perl/packages/devel/Math-BigInt-1.74.tar.gz As for FastCalc failing, I intent to deprecate that package. It really doesn't speed things up much, but creates tons of problems due to XS. If you look for a lib to replace Calc, please use 'GMP', it scales much better and is quite stable now. :o) Best wishes, Tels - -- Signed on Sun Dec 19 16:58:50 2004 with key 0x93B84C15.
