Thank you for taking the time to write to us, but this is not
a bug. Please double-check the documentation available at
http://www.php.net/manual/ and the instructions on how to report
a bug at http://bugs.php.net/how-to-report.php

there are quite a few bug reports on this.

adding floats can produce unpredicable results
you could try using bcmath or sprintf

$temp=-1.0;
for($i=0;$i<=10;$i++){
$temp=(float) sprintf("%.2f",$temp+0.2);
echo "<br>".$temp;
}

<?php

for($i=0;$i<=10;$i++)
{
$temp=$temp+0.2;
echo "<br>".$temp;
}
?>
