RE: Weird results of "=="

<?

$a = 252.73;
$b = 252.73;
$c = 0;

if ($a == ($b + $c))
{
// do the first thing
}
elseif ($a > ($b + $c))
{
// do the second thing
}
elseif ($a < ($b + $c))
{
// do the third thing
}

?>

Each of the three variables is derived by some earlier calculation, but
for
testing purposes I have made sure that they end up being $a = $b and $c
= 0.
I have tested for three different values (of $a) and gotten all three
results. That is, once the first block has executed, once the second
block
and once the third block.

Am I missing something really obvious here?

How do I execute only the first block if indeed $a == ($b + $c) ?

When I tested this code only the first block executed.
