Integers that do not have an exact double representation will silently result in a loss of precision. Integers that cause a double overflow will cause an error. JSON_ALLOW_NUL Allow \u0000 escape inside string values. This is a safety measure; If you know your input can contain null bytes...

``parse_int``, if specified, will be called with the string of every JSON int to be decoded. By default this is equivalent to int(num_str). This can be used to use another datatype or parser for JSON integers (e.g. float). ``parse_constant``, if specified, will be called with...
for JSON integers (e.g. float). ``parse_constant``, if specified, will be called with one of the following strings: -Infinity, Infinity, NaN. This can be used to raise an exception if invalid JSON numbers are encountered. To use a custom ``JSONDecoder`` subclass, specify it with the...
The BSON mapping has added support for unsigned 64-bit integers. #4590 #4535 #3894 The get_number function used in the binary format implementations has been optimized to read multiple bytes at once. #4391 Multidimensional array conversion: Multidimensional C-style arrays can now be directly conve...
container (std::array, std::vector, std::deque, std::forward_list, std::list) whose values can be used to construct JSON values (e.g., integers, floating point numbers, Booleans, string types, or again STL containers described in this section) can be used to create a JSON array. Th...
