.SH "DESCRIPTION"
.IX Header "DESCRIPTION"
This module provides a \s-1BSON\s0 type wrapper for a numeric value that
would be represented in \s-1BSON\s0 as a 64\-bit integer.
.PP
If the value won't fit in a 64\-bit integer, an error will be thrown.
.PP
On a Perl without 64\-bit integer support, the value must be a
Math::BigInt object.
.SH "ATTRIBUTES"
.IX Header "ATTRIBUTES"
.SS "value"
.IX Subsection "value"
A numeric scalar.  It will be coerced to an integer.  The default is 0.
.SH "METHODS"
.IX Header "METHODS"
.SS "\s-1TO_JSON\s0"
.IX Subsection "TO_JSON"
On a 64\-bit perl, returns the value as an integer.  On a 32\-bit Perl, it
will be returned as a Math::BigInt object, which will
fail to serialize unless a \f(CW\*(C`TO_JSON\*(C'\fR method is defined
for that or in package \f(CW\*(C`universal\*(C'\fR.
.PP
If the \f(CW\*(C`BSON_EXTJSON\*(C'\fR environment variable is true and the
\&\f(CW\*(C`BSON_EXTJSON_RELAXED\*(C'\fR environment variable is false, returns a hashref
compatible with
MongoDB's extended \s-1JSON\s0 <https://github.com/mongodb/specifications/blob/master/source/extended-json.rst>
format, which represents it as a document as follows:

.SH "OVERLOADING"
.IX Header "OVERLOADING"
The numification operator, \f(CW\*(C`0+\*(C'\fR is overloaded to return the \f(CW\*(C`value\*(C'\fR,
the full \*(L"minimal set\*(R" of overloaded operations is provided (per overload
documentation) and fallback overloading is enabled.
