BloombergLP::bdljsn::JsonNumber::asShort

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.
