note syphilis <I>Please consider assisting them by taking the survey about your participation in the Perl/Raku community.</I><br><br> Considered ... and declined. <br> Raku provided the opportunity to drag perl into the 21st century but, in terms of the way that numbers are handled, they opted to stick with an approach that I would term "neanderthal". <br> So I quickly lost interest. (But that's only because the way that numbers are handled is important to me ... and I do realize that there are others with different priorities.) <br><br>To elaborate, here's the approach that python3 chose to follow: <c> \$ cat demo.py from fractions import Fraction; print (Fraction(1, 10) == 0.1); # False print (Fraction(3602879701896397, 36028797018963968) == 0.1); # True \$ python3 demo.py False True </c> And here's the approach that raku has elected to follow: <c> C:\_32>type demo.r my \$x = 1/10; say \$x.nude; my \$y = 3602879701896397/36028797018963968; say \$y.nude; say \$x == 0.1e0; say \$y == 0.1e0; say \$y == \$x; C:\_32>raku demo.r (1 10) (3602879701896397 36028797018963968) True True False </c> <strike><c> >type demo.r say 1/10 == 0.1e0; say 3602879701896397/36028797018963968 == 0.1e0; >raku demo.r True True </c></strike> Both the raku and python3 scripts are comparing the same rationals to the same double precision floating point value, and yet they provide different results. <br><br>Sure, I get that both of the rationals (1/10 and 3602879701896397/36028797018963968) round to the same double precision floating point value - and that's why raku reports "True" in both instances. <br>But the thing is that the double 0.1 does have a precise and exact rational value - and that precise and exact rational value is 3602879701896397/36028797018963968 (or, in decimal, 0.1000000000000000055511151231257827021181583404541015625) and not the precise and exact rational value of 1/10 (in decimal, 0.1). <br><br>I don't know why raku has made this choice. Anyone ? <br>The most annoying thing about it is that it implies that (the rational) 1/10 == (the rational) 3602879701896397/36028797018963968 ... yet raku itself will tell you that isn't so (if you explicitly ask it about that). <br><br>I'm inclined to think that it was done simply to annoy me ... though, somewhere deep inside, I think that even I realize that I'm probably not quite that important ;-) <br><br>Cheers,<br>Rob 11137153 11137153
