Maybe this?

<?php

$num = '49.82';
$new_num = $num;

$hundredth = substr($num, -1, 1);

switch($hundredth)
{
    case '0':
        break;
    case '1':
        $new_num = ($new_num - 0.01);
        break;
    case '2':
        $new_num = ($new_num - 0.02);
        break;
    case '3':
        $new_num = ($new_num - 0.03);
        break;
    case '4':
        $new_num = ($new_num - 0.04);
        break;
    case '5':
        break;
    case '6':
        $new_num = ($new_num + 0.04);
        break;
    case '7':
        $new_num = ($new_num + 0.03);
        break;
    case '8':
        $new_num = ($new_num + 0.02);
        break;
    case '9':
        $new_num = ($new_num + 0.01);
        break;
}

echo $new_num;

?>
