Well apparently not with win32 5.6 : `#!perl use strict ; use warnings; my $bignum = Math::BigInt->new('1111111111111111111111111'); $bignum->as_hex(); print $bignum ;` [download] gives : `Can't locate object method "new" via package "Math::BigInt" (perhaps y +ou forgot to load "Math::BigInt"?) at t.pl line 4.` [download] as_hex is not in the doc, either, but i indeed saw it with 5.8	[reply] [d/l] [select]

So you are using an older version of the module, you should upgrade the module if you want this functionality.	[reply]

no. it will run on a large number of machines and i have no possibility to upgrade them all, moreover for a single functionality.	[reply]

There's an important clue in the error message: you need to `use Math::Bigint;` (or `use bigint;`). But if you aren't already doing that, what do you mean by a "bigint number"? Oh, I see; you perhaps are using the ancient decrepit perl4-ish bigint.pl; you are strongly advised to install a new version of Math::BigInt (which I believe includes a bigint.pm module also) which has scads of bug fixes and use it instead. You also should be doing `print $bignum->as_hex();`; just calling it in void context doesn't do anything.	[reply] [d/l] [select]

you perhaps are using the ancient decrepit perl4-ish bigint.pl I'm using active perl 5.6, and as far as i understand it as_hex is not in the methods offered : BigInt ActiveState Sadly upgrading is not an option here. How can do it ? I'm trying to divide by 16 as in a standard conversion but it doesn't work very well ...	[reply]

err, sorry ! Here it is : `#!perl use strict ; use warnings; use Math::BigInt ; my $bignum = Math::BigInt->new('1111111111111111111111111'); $bignum->as_hex(); print $bignum ;` [download] gives `Can't locate object method "as_hex" via package "Math::BigInt" (perhap +s you forgot to load "Math::BigInt"?) at t.pl line 6.` [download]	[reply] [d/l] [select]
