Ahem, this is about 0.1 + 0.2. I think Raku also uses IEEE 754 double precision floating point numbers for the Num type, no? Edit: it seems that Raku uses rationals as a default [1], so it doesn't suffer from the same problem by default. [1]: https://0.30000000000000004.com/#raku |

Yeah, exactly, Raku defaults to a rational number type for these kinds of numbers. I honestly think that is a perfectly fine way to do it, you're not using Raku for high performance stuff anyway. It's not so different from how Python will start to use arbitrarily sized integers if it feels it needs to.
Raku by default will convert it to a float if the denominator gets larger than a 64-bit int, but there's actually a current pull request active that lets you customize that behavior to always keep it as a Rat.
Really interesting language, Raku!
