Re^3: big integers forcing me to be a C programmer: "range iterator outside integer range"

Well, I never said "unsigned" :) But it's a point worth making. Though on my system the limits are somewhat different:

] Perl> print for 1 .. 2**62;;
1
2
3
4
5
6
7
8
9
10
11
[download]

I won't post the rest, so you'll have to take my word that it does actually get beyond 2**31-2 :)

Examine what is said, not who speaks -- Silence betokens consent -- Love the truth but pardon error.

"Science is about questioning the status quo. Questioning authority".

In the absence of evidence, opinion is indistinguishable from prejudice.

Lucky man. You have a 64 bit machine, I bet ... ;-)	[reply]

You don't need a 64-bit machine to have Perl be able to perform 64 bit integer arithmetic. You need a compiler who's able to deal with 64-bit arithmetic (you can even have a compiler that isn't able to produce binaries able to use 64 bit arithmetic on 64 bit platforms - for instance, SUN produced 64 bit platforms years before gcc was able to deal with 64 bit integers). And then when compiling Perl, enable the 64 bit integers.	[reply]
