Hi, Some anomalous rounding behaviour on Ubuntu-16.04 was noted at http://www.perlmonks.org/?node_id=1200326 Here are the specifics: $ perl6 --version This is Rakudo version 2017.07 built on MoarVM version 2017.07 implementing Perl 6.c. ======= Issue 1 ======= $ perl6 -e 'say Int(2e25);' 20000000000000001811939328 $ perl6 -e 'say Int(20e24);' 19999999999999997516972032 That seems odd because 2e25 and 20e24 are exactly equivalent. ======= Issue 2 ======= $ perl6 -e 'say "WTF" if 1.000000000000001e0 == 1e0;' WTF That seems odd because 1.000000000000001e0 and 1e0 are quite different double precision values. According to perl5: $ perl -le 'print scalar reverse unpack "h*", pack "d<", 1.000000000000001e0;' 3ff0000000000005 $ perl -le 'print scalar reverse unpack "h*", pack "d<", 1e0;' 3ff0000000000000 Is it the intention of the perl6 developers that such discrepancies will be addressed ? Cheers, Rob
