When I look at this, I find myself wanting to separate the control from the
data. Here's an alternative:

my @input  = qw( 4.5   0.0   13.12343 );
my @output = qw( 4.5   0.0   13.12343 ); # can't assume that input==output

my $code = join(";", map {"print $_"} @input);
my $expect = join( "", @output);
output_is($code, $expect, "Simple Floats");

This is, perhaps, slightly harder to grok initially. But its easier to
extend the test data; and also to make control-path changes (such as added
the \n to the print statement). It might be better to use a hash for the
test data.

It is possible to make this type of test much easier to read. A mechanism I
have used in the past is to put the test data into a table (I used html).
Then, you have the test data and expected output as a nice table in a
document; and a simple piece of code to extract tests from it (assuming you
use a perl5 module to parse the table).
