BSON type for the
|
|||
|
|
<link xlink:href="&url.mongodb.wiki.decimal128;">Decimal128 floating-point format</link>,
|
|||
|
|
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. <type>float</type> in PHP), which only
|
|||
|
|
stores an approximation of the decimal values, the decimal data type stores
|
|||
|
|
the exact value. For example, <literal>MongoDB\BSON\Decimal128('9.99')</literal>
|
|||
|
|
has a precise value of 9.99 where as a double 9.99 would have an approximate
|
|||
|
|
value of 9.9900000000000002131628….
