Hi,
I'm pretty sure that your expectation of the result of
print sprintf("%0.02f",0.345);
is a little bit wrong. 0.345 rounded to two digits after the comma is 0.35 and not 0.34. You hit a classical floating point rounding error, Have a look at:
perl -E 'print sprintf("%0.18f",0.346);'
If you do mathematics with this kind of rounding error you can be hit by such a phaenomena.
UPDATE: Look at this:
#!/usr/bin/env perl
use strict;
use warnings;
use 5.010;
use Data::Dumper;
my $l8 = 3.49;
my $l7 = 2;
my $subprice = 1.4;
my $tprice;
$tprice = ($l8/$l7)-$subprice;
if ($tprice < 1 && length($tprice) > 4) {
print "SPRINTF - $tprice - " . sprintf("%0.18f",$tprice) . "\n";
}

Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big>
<blockquote> <br /> <dd>
<dl> <dt> <em> <font>
<h1> <h2> <h3> <h4>
<h5> <h6> <hr /> <i>
<li> <nbsp> <ol> <p>
<small> <strike> <strong>
<sub> <sup> <table>
<td> <th> <tr> <tt>
<u> <ul>
-
Snippets of code should be wrapped in
<code> tags not
<pre> tags. In fact, <pre>
tags should generally be avoided. If they must
be used, extreme care should be
taken to ensure that their contents do not
have long lines (<70 chars), in order to prevent
horizontal scrolling (and possible janitor
intervention).
