Problem with float canonization

[danielmarschall]

Hello,
In src/Utils.php at method es6NumberFormat(), I have found these two lines:

        $formatted = rtrim($formatted, '.0');

and

        $parts[0] = rtrim($parts[0], '.0');

I think they are not doing what they are intended for. Here, all "0" and "." are removed from the right side of the string.
But zeros left to the decimal point will be removed too. This means that the number 1230.0000 will become 123 and not 1230.

I think this will work:

$formatted = rtrim($formatted, '0'); // first remove all zeros at the end
$formatted = rtrim($formatted, '.'); // If the string now ends with a decimal point, then remove it, too.

and

$parts[0] = rtrim($parts[0], '0'); // first remove all zeros at the end
$parts[0] = rtrim($parts[0], '.'); // If the string now ends with a decimal point, then remove it, too.

Checking str_contains(..., '.') is not required, since sprintf('%e', ...) and sprintf('%F', ...) ensures that there is a decimal point.
