It's been about 15 years since I've written any Pascal, but here you go...
program floating;
var
A, B :real;
begin
A := 14.4e0;
B := 10.0e0 + 14.4e0 - 10.0e0;
writeln( A );
writeln( B );
if A = B then
writeln('they are equal')
else
writeln('they differ');
end.
Compiled using Free Pascal Compiler 2.6.2-5 (i386), I get the following output:
1.44000000000000E+001
1.44000000000000E+001
they are equal
I don't know if FPC is especially smart at optimizing the mathematical expressions, or especially smart at DWIM output and comparisons on floating point numbers. But it's being smart somehow.
use Moops; class Cow :rw { has name => (default => 'Ermintrude') }; say Cow->new->name

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).
