BloombergLP::bdljsn::JsonNumber

This class defines a value‐semantic type that represents a JSON number.

Synopsis

Declared in <bdljsn_jsonnumber.h>

class JsonNumber;

Description

Objects of this class have a value determined at construction and does not change except by assignment from or swap with another JsonNumber object. The value can be specified by supplying a string that conforms to the {JSON Textual Specification} or from one of the {Supported Types}. The value of a JSON object can be converted to any of those types; however, some of those conversions can be inexact.
