Re^5: Can I access and use UV types from perl? (updated)

bignum still appears to store the value as an IV though.

No, they're objects*. See the output of perl -Mbignum -MDevel::Peek -e 'my $x=1; Dump($x)' or perl -Mbignum -MData::Dump -e 'my $x=1; dd($x)'.

It would seem that some kind of overloading solution may be the way to go, let Perl handle the storage, but overload the operations with XSUBS that do type checking/coercion. Or even straight up Inlining C.

Well, again, if you don't tell us what for, we can't really comment.

* Update: I guess you maybe mean internally? The point is, how they're stored internally is abstracted and encapsulated in an object, and you shouldn't worry about it. bignum will allow you to work with numbers of any size and any precision without any loss due to the usual floating-point imprecisions, overflows, etc.

for the greater understanding and enoblement of homus erectus. That and, well one reason may be to help with the documentation on the `Rat()` function in Perl 6. By understanding what Perl is doing with numbers at the level of the Naturals we can possibly figure out how to convert the Rationals into Reals and update the Docs accordingly. Well that and just sanity in general.	[reply] [d/l]

That and, well one reason may be to help with the documentation on the `Rat()` function in Perl 6. My understanding from a quick look at the Raku (formerly known as Perl 6) documentation is: `int` is a native integer, so like Perl's `IV` `Int` is like Perl's Math::BigInt (bignum; note that enables Math::BigFloats too) `Num` is a native float, so like Perl's `NV` `Rat` is basically like two integers for numerator and denominator, overflowing causes it to be cast to `Num` (which seems like a downgrade to me) `FatRat` is like Perl's Math::BigRat (bigrat) I don't see an equivalent of Math::BigFloat in Raku at the moment. By understanding what Perl is doing with numbers at the level of the Naturals I think Perl's data types are much more closely aligned with the underlying native types than with mathematical concepts like natrual numbers, whole numbers, etc. we can possibly figure out how to convert the Rationals into Reals According to the docs, `role Rational[::NuT, ::DeT] does Real { ... }` already...?
