To conform with RFC 4627, RapidJSON supports string containing U 0000 character. The problem is that, C/C often uses null-terminated string, which treats \0 as the terminator symbol. Here explains why:Īccording to RFC 4627, JSON strings can contain Unicode character U 0000, which must be escaped as "\u0000". In addition to GetString(), the Value class also contains GetStringLength(). Note that, int and unsigned can be safely converted to double, but int64_t and uint64_t may lose precision (since mantissa of double is only 52-bits). When obtaining the numeric values, GetDouble() will convert internal integer representation to a double. But a value y containing -3000000000 will only make x.IsInt64() = true. ![]() For example, A value x containing 123 will make x.IsInt() = x.IsUint() = x.IsInt64() = x.IsUint64() = true. Note that, an integer value may be obtained in various ways without conversion. When querying a number, you can check whether the number can be obtained as the target type: Checking When a Number is parsed, it is stored in the DOM as one of the following types: Type ![]() RFC 4627 says the range of Number is specified by the parser implementation.Īs C provides several integer and floating point number types, the DOM tries to handle these with the widest possible range and good performance. Number can be an integer or a real number. JSON provides a single numerical type called Number.
