float validation failure with trailing Zero

[pascal-larocque]

Seems that strings with trailing Zero do not validate correctly

Inspekt::isFloat("1.60") === false
floatval() trims the trailing Zero
strval(1.6) !== "1.60"

[pascal-larocque]

Should fix it
` /**
* Returns true if value is a valid float value, false otherwise.
*
* @param string $value
* @return boolean
*
* @Assert(10244578109.234451) === true
* @Assert('1.60') === true
* @Assert('1.00') === true
* @Assert('10244578109.234451') === false
* @Assert('10,244,578,109.234451') === false
*

public static function isFloat($value)

$locale = localeconv();
$value = str_replace($locale['decimal_point'], '.', $value);
$value = str_replace($locale['thousands_sep'], '', $value);
$value = rtrim($value,'0');
$value = rtrim($value,'.');

    return (strval(floatval($value)) === $value);
