Load into the specified result the integer value of the value of type JsonNumber held by this object. Return 0 on success, JsonNumber::k_OVERFLOW if value is larger than can be represented by result, JsonNumber::k_UNDERFLOW if value is smaller than can be represented by result, and JsonNumber::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 value to the nearest integer). 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 a status value (unlike similar floating point conversions) because typically it is an error if a conversion to an integer results in an inexact value. The behavior is undefined unless isNumber() returns true. Also note that on all supported platforms bsls::Types::Int64 and bsls::Types::Uint64 are, respectively, aliases for long long and unsigned long long.
