Re: Best way to check for 64-bit support

With Config.pm you could check for d_quad. Another funny way to find the internal integer size is

perl -E 'say unpack "%b*", pack "j", -1'

similar idea, slightly shorter :) `DB<10> p length sprintf '%b',-1 64` [download] but reliability may be effected by various math pragmas ... Cheers Rolf _{(addicted to the Perl Programming Language :) Wikisyntax for the Monastery}	[reply] [d/l]
