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
