Code:
say 255.base(16, -100);

Result:
FF.

Docs say (http://doc.perl6.org/routine/base#role_Real):
“The optional $digits argument asks for that many digits of fraction (which
may not be negative).”
So there is something wrong.


And also our classic stuff:
Code:
say 255.base(16, 9999999999999999999999999999999999999999999999999);

Result:
repeat count (-537617205517352961) cannot be negative
  in block <unit> at ./test.pl:2
