You can modify your function to fullfil both your need to force a unit if given and adjust the precision.

function humanFileSize($size, $precision = 1, $show = "")
{
    $b = $size;
    $kb = round($size / 1024, $precision);
    $mb = round($kb / 1024, $precision);
    $gb = round($mb / 1024, $precision);

    if($kb == 0 || $show == "B") {
        return $b . " bytes";
    } else if($mb == 0 || $show == "KB") {
        return $kb . "KB";
    } else if($gb == 0 || $show == "MB") {
        return $mb . "MB";
    } else {
        return $gb . "GB";
    }
}

//Test with different values
echo humanFileSize(1038) . "
";    
echo humanFileSize(103053, 0) . "
";
echo humanFileSize(103053) . "
";
echo humanFileSize(1030544553) . "
";
echo humanFileSize(1030534053405, 2, "GB") . "
";  ;
