PHP 8.4.1 Released!

    The MongoDB\BSON\Decimal128 class

    (mongodb >=1.2.0)

    Einführung

    BSON type for the » Decimal128 floating-point format, which supports numbers with up to 34 decimal digits (i.e. significant digits) and an exponent range of −6143 to +6144.

    Unlike the double BSON type (i.e. float in PHP), which only stores an approximation of the decimal values, the decimal data type stores the exact value. For example, MongoDB\BSON\Decimal128('9.99') has a precise value of 9.99 where as a double 9.99 would have an approximate value of 9.9900000000000002131628….

    Hinweis: MongoDB\BSON\Decimal128 ist nur mit MongoDB 3.4+ kompatibel. Der Versuch, den Typ BSON mit einer früheren Version von MongoDB zu verwenden, führt zu einem Fehler.
