NAME

       BSON::Decimal128 - BSON type wrapper for Decimal128

VERSION

       version v1.4.0

SYNOPSIS

           use BSON::Types ':all';

           # string representation
           $decimal = bson_decimal128( "1.23456789E+1000" );

           # binary representation in BID format
           $decimal = BSON::Decimal128->new( bytes => $bid )

DESCRIPTION

       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.

ATTRIBUTES

   value
       The Decimal128 value represented as string.  If not provided, it will be generated from
       the "bytes" attribute on demand.

   bytes
       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.

METHODS

   TO_JSON
       Returns the value as a string.

       If the "BSON_EXTJSON" option is true, it will instead be compatible with MongoDB's
       extended JSON <https://docs.mongodb.org/manual/reference/mongodb-extended-json/> format,
       which represents it as a document as follows:

           {"$numberDecimal" : "2.23372036854775807E+57"}

OVERLOADING

       The stringification operator ("") is overloaded to return a (normalized) string
       representation. Fallback overloading is enabled.
