With this program:
[code]
#!/usr/bin/perl
use strict;
use warnings;
my $d1 = 6.892964e-309;
my $d2 = 1.102874e-307;
my $sum = $d1 + $d2;
printf "d1 = %e\n", $d1;
printf "d2 = %e\n", $d2;
printf "sum = %e\n", $sum;
[/code]
I'm getting:
[outout]
d1 = 0.000000e+00
d2 = 1.000000e-307
sum = 1.000000e-307
[/output]
On Mandriva Linux Cooker on an x86 (with perl-5.12.2-4mdv2011.0 ) and Mandriva
Linux 2010.1 on an x86-64 (perl-5.10.1-10mdv2010.1).
