    BcMath\Number::compare — Compares two arbitrary precision numbers

    Açıklama

    public BcMath\Number::compare(BcMath\Number|string|int $num, ?int $scale = null): int

    Compare two arbitrary precision numbers. This method behaves similar to the spaceship operator.

    Bağımsız Değişkenler

    num
    The value to be compared to.
    scale
    Specify the scale to use for comparison. If null, all digits are used in the comparison.

    Dönen Değerler

    Returns 0 if the two numbers are equal, 1 if $this is greater than num, -1 otherwise.

    Hatalar/İstisnalar

    This method throws a ValueError in the following cases:

    • num is string and not a well-formed BCMath numeric string
    • scale is outside the valid range

    Örnek 1 BcMath\Number::compare() example when scale is not specified

    <?php
    $number     = new BcMath\Number('1.234');

    var_dump(
    $number->compare(new BcMath\Number('1.234')),
    $number->compare('1.23400'),
    $number->compare('1.23401'),
    $number->compare(1),
    );
    ?>

    Yukarıdaki örneğin çıktısı:

    int(0)
int(0)
int(-1)
int(1)

    Örnek 2 BcMath\Number::compare() example of explicitly specifying scale

    <?php
    $number     = new BcMath\Number('1.234');

    var_dump(
    $number->compare(new BcMath\Number('1.299'), 1),
    $number->compare('1.24', 2),
    $number->compare('1.22', 2),
    $number->compare(1, 0),
    );
    ?>

    Yukarıdaki örneğin çıktısı:

    int(0)
int(-1)
int(1)
int(0)
