BSON::Decimal128 - BSON type wrapper for Decimal128
version v1.12.2
use BSON::Types ':all';
# string representation
$decimal = bson_decimal128( "1.23456789E+1000" );
# binary representation in BID format
$decimal = BSON::Decimal128->new( bytes => $bid )
This module provides a BSON type wrapper for Decimal128 values.
It may be initialized with either a numeric value in string form, or with a
binary Decimal128 representation (16 bytes), but not both.
Initialization from a string will throw an error if the string cannot be parsed
as a Decimal128 or if the resulting number would not fit into 128 bits. If
required, clamping or exact rounding will be applied to try to fit the value
into 128 bits.
The Decimal128 value represented as string. If not provided, it will be
generated from the "bytes" attribute on demand.
The Decimal128 value represented in Binary Integer Decimal
<
https://en.wikipedia.org/wiki/Binary_Integer_Decimal> (BID) format. If
not provided, it will be generated from the "value" attribute on
demand.
Returns the value as a string.
If the "BSON_EXTJSON" option is true, it will instead be compatible
with MongoDB's extended JSON
<
https://github.com/mongodb/specifications/blob/master/source/extended-json.rst>
format, which represents it as a document as follows:
{"$numberDecimal" : "2.23372036854775807E+57"}
The stringification operator ("") is overloaded to return a
(normalized) string representation. Fallback overloading is enabled.
