->signum() bug

[FoxKeys]

Looks like i have found a bug. signum() for zero expected to be a zero. But, it is returns 1.

decimal support | enabled
decimal version | 1.1.0
libmpdec version | 2.4.2

Test code:

    $a = new Decimal(0);
    print_r($a);
    echo 'isZero? ', var_export($a->isZero(), true), "\n";
    echo 'signum: ', $a->signum(), "\n";
    $a = new Decimal(1);
    print_r($a);
    echo 'isZero? ', var_export($a->isZero(), true), "\n";
    echo 'signum: ', $a->signum(), "\n";
    $a = new Decimal(-1);
    print_r($a);
    echo 'isZero? ', var_export($a->isZero(), true), "\n";
    echo 'signum: ', $a->signum(), "\n";

Output:

Decimal\Decimal Object
(
    [value] => 0
    [precision] => 28
)
isZero? true
signum: 1
Decimal\Decimal Object
(
    [value] => 1
    [precision] => 28
)
isZero? false
signum: 1
Decimal\Decimal Object
(
    [value] => -1
    [precision] => 28
)
isZero? false
signum: -1
