How to reproduce ---------------- perl6 -e 'my ($a, $b) = set(1e0), set(1e0 + 4e-15); say $a ~~ $b, $a.keys »≅« $b.keys' Expected behavior ----------------- Prints `False(False)`. Actual behavior --------------- Prints `True(False)`. This contradicts the documentation of the Setty ACCEPTS method: “Returns True if $other and self contain all the same elements, and no others.” The sets’ elements aren’t equal, or even approximately equal (≅), and yet ACCEPTS (~~) returns `True`. Note that other set methods show similar behavior: `1e0 ⊖ (1e0 + 4e-15)` is the empty set, `set(1e0, 1e0 + 4e-15)` only has one element… Version information ------------------- This is Rakudo version 2017.09 built on MoarVM version 2017.09.1 implementing Perl 6.c.
