This class defines a value-semantic class that represents a JSON number. 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.
See bdljsn_jsonnumber
Load to the specified result the closest floating point representation to this number, even if a non-zero status is returned. Return 0 if this number can be represented exactly, and return k_INEXACT and load result with the closest approximation if value cannot be represented exactly. If this number is outside the representable range, load result with +INF or -INF (as appropriate). A number can be represented exactly as a Decimal64 if, for the significand and exponent, abs(significand) <= 9,999,999,999,999,999 and -398 <= exponent <= 369.

Load into the specified result the integer value of this number. Return 0 on success, k_OVERFLOW if value is larger than can be represented by result, k_UNDERFLOW if value is smaller than can be represented by result, and k_NOT_INTEGRAL if value is not an integral number (i.e., there is a fractional part). For underflow, result will be loaded with the minimum representable value, for overflow, result will be loaded with the maximum representable value, for non-integral values result will be loaded with the integer part of value (truncating the fractional part). If the result is not an integer and also either overflows or underflows, it is treated as an overflow or underflow (respectively). Note that this operation returns an error status value (unlike similar floating point conversions) because typically it is an error if a conversion to an integer results in an in-exact value.

Return true if this number and the specified other number represent the same numeric value, and false otherwise. This method will return true for differing representations of the same number (e.g., 1.0, "1", "0.1e+1" are all equivalent) except in cases where the exponent cannot be represented by a 64-bit integer. If the exponent is outside the range of a 64-bit integer, true will be returned if *this == other. For example, comparing "1e18446744073709551615" with itself will return true, but comparing it to "10e18446744073709551614" will return false. Note that this method is more computationally expensive than the equality and inequality operators.

Write the value of this object to the specified output stream in a human-readable format, and return a non-const reference to stream. Optionally specify an initial indentation level, whose absolute value is incremented recursively for nested objects. If level is specified, optionally specify spacesPerLevel, whose absolute value indicates the number of spaces per indentation level for this and all of its nested objects. If level is negative, suppress indentation of the first line. If spacesPerLevel is negative, format the entire output on one line, suppressing all but the initial indentation (as governed by level). If stream is not valid on entry, this operation has no effect. Note that the format is not fully specified, and can change without notice.
