-distinguish the stored values, and the functions @ref basic_json::is_null(),
-@ref basic_json::is_object(), @ref basic_json::is_array(),
-@ref basic_json::is_string(), @ref basic_json::is_boolean(),
-@ref basic_json::is_number() (with @ref basic_json::is_number_integer(),
-@ref basic_json::is_number_unsigned(), and @ref basic_json::is_number_float()),
-@ref basic_json::is_discarded(), @ref basic_json::is_primitive(), and
-@ref basic_json::is_structured() rely on it.
-
-@note There are three enumeration entries (number_integer, number_unsigned, and
-number_float), because the library distinguishes these three types for numbers:
-@ref basic_json::number_unsigned_t is used for unsigned integers,
-@ref basic_json::number_integer_t is used for signed integers, and
-@ref basic_json::number_float_t is used for floating-point numbers or to
-approximate integers which do not fit in the limits of their respective type.
-

-value with the default value for a given type

- @brief scan a number literal
-
- This function scans a string according to Sect. 6 of RFC 8259.
-
- The function is realized with a deterministic finite state machine derived
- from the grammar described in RFC 8259. Starting in state "init", the
- input is read and used to determined the next state. Only state "done"
- accepts the number. State "error" is a trap state to model errors. In the
- table below, "anything" means any character but the ones listed before.
-
- state | 0 | 1-9 | e E | + | - | . | anything
- ---------|----------|----------|----------|---------|---------|----------|-----------
- init | zero | any1 | [error] | [error] | minus | [error] | [error]
- minus | zero | any1 | [error] | [error] | [error] | [error] | [error]
- zero | done | done | exponent | done | done | decimal1 | done
- any1 | any1 | any1 | exponent | done | done | decimal1 | done
- decimal1 | decimal2 | decimal2 | [error] | [error] | [error] | [error] | [error]
- decimal2 | decimal2 | decimal2 | exponent | done | done | done | done
- exponent | any2 | any2 | [error] | sign | sign | [error] | [error]
- sign | any2 | any2 | [error] | [error] | [error] | [error] | [error]
- any2 | any2 | any2 | done | done | done | done | done
-
- The state machine is realized with one label per state (prefixed with
- "scan_number_") and `goto` statements between them. The state machine
- contains cycles, but any cycle can be left when EOF is read. Therefore,
- the function is guaranteed to terminate.
-
- During scanning, the read bytes are stored in token_buffer. This string is
- then converted to a signed integer, an unsigned integer, or a
- floating-point number.
-
- @return token_type::value_unsigned, token_type::value_integer, or
- token_type::value_float if number could be successfully scanned,
- token_type::parse_error otherwise
-
- @note The scanner is independent of the current locale. Internally, the
- locale's decimal point is used instead of `.` to work with the
- locale-dependent converters.

- container's elements must have the current value as parent.
-
- @param[in] check_parents whether the parent relation should be checked.
- The value is true by default and should only be set to false
