bash-2.02$ j.pl
same
bash-2.02$ 

So == works but looks like sybase is not returning the same floatie to you
every time. :-)

I think the best would be to comment out that line itself.

Floats don't like you it seems. ;)

Just for grins, I tried to make the check match the returned
result exactly:

solaris8:1:46 [/.cpan/build/DBD-Sybase-1.07] # sed -n '85,90p' t/exec.t
$rc = $sth->execute(undef, 25, 3.2234, "jan 3 2001", 5.4);
ok(defined($rc), "exec dbitest 3");
my @out = $sth->func('syb_output_params');
#print "@out\n";
ok($out[0] == 5.40000000000000035527136788005009, "out param 1");

But it still fails:

solaris8:1:47 [/.cpan/build/DBD-Sybase-1.07] # make test
PERL_DL_NONLAZY=1 /usr/bin/perl "-MExtUtils::Command::MM" "-e" 
"test_harness(0, 'blib/lib', 'blib/arch')" t/*.t
t/autocommit....ok
t/base..........ok
t/exec..........NOK 11
#     Failed test (t/exec.t at line 89)
# Looks like you failed 1 test of 22.
t/exec..........dubious
         Test returned status 1 (wstat 256, 0x100)
DIED. FAILED test 11
         Failed 1/22 tests, 95.45% okay

Maybe it's not comparing "$out[0]" to the 5.400000... as a
float vs. float?
