    That's interesting - I thought that raku was above producing that sort of braindead bullshit.
    Is it rounding to the nearest integer ?
    Or maybe it's doing decimal math ?

    UPDATE: aaah ... I think I get it ... 1.15 is being evaluated as the rational value 115/100 ... right ?

    Cheers,

      Yes, Raku has a Rat type which stores (and normalizes) numerator and denominator. Legend has it they only did that so they can have a .nude method (which returns a Pair).

        I find it confusing that a bareword of 1.15 can be assigned exactly as the rational 115/100 rather than as the approximated double.
        But I guess that one would adapt quickly enough to the change of mindset, if one had to.
