@brief check whether Clinger's fast path can still succeed for this token
parse_float_fast() needs a significand below 2^53. A mantissa with 17 or
more significant digits is at least 10^16 and therefore always exceeds it,
so calling the fast path would walk the token one extra time only to
decline before strtod has to run anyway.
Significant digits are the mantissa's digits from the first nonzero one on;
the sign, the decimal point, leading zeros, and the exponent do not count.
The answer is derived from indices - the digits are not scanned again - so
this stays off the hot path of the number scanners.

@brief convert the float in token_buffer with strtof/strtod/strtold
These functions expect the decimal point of the *current* locale, so it is
looked up right before the conversion instead of once when the lexer is
constructed: a locale change in between (by a parser callback, a SAX
handler, or another thread) must not truncate the value (#5198). The
token has been validated before, so if the conversion stops early and the
decimal point changed in the meantime, the locale changed between the
lookup and the call, and the conversion is repeated with the new decimal
point. If the decimal point did not change, a retry cannot succeed: the
locale's decimal point is not a single character (e.g., the two-byte
U+066B of ar_EG.UTF-8 or fa_IR.UTF-8) and cannot be substituted in place.
The value strtod parsed up to that point is kept, as before this change.
Note that changing the locale in another thread *while* strtod runs is
undefined behavior of the C library, which this function cannot prevent.

@brief check whether Clinger's fast path can still succeed for a float token
parse_float_fast() needs a significand below 2^53. A mantissa with 17 or
more significant digits is at least 10^16 and therefore always exceeds it,
so calling the fast path would walk the token one extra time only to
decline before strtod has to run anyway.
Significant digits are the mantissa's digits from the first nonzero one on;
the sign, the decimal point, leading zeros, and the exponent do not count.
The answer is derived from indices - the digits are not scanned again - so
this stays off the hot path of the number scanners.

@brief convert a validated float token with strtof/strtod/strtold
These functions expect the decimal point of the *current* locale, so it is
looked up right before the conversion instead of once when the lexer is
constructed: a locale change in between (by a parser callback, a SAX
handler, or another thread) must not truncate the value (#5198). The
token has been validated before, so if the conversion stops early and the
decimal point changed in the meantime, the locale changed between the
lookup and the call, and the conversion is repeated with the new decimal
point. If the decimal point did not change, a retry cannot succeed: the
locale's decimal point is not a single character (e.g., the two-byte
U+066B of ar_EG.UTF-8 or fa_IR.UTF-8) and cannot be substituted in place.
The value strtod parsed up to that point is kept, as before this change.
Note that changing the locale in another thread *while* strtod runs is
undefined behavior of the C library, which this function cannot prevent.

decimal point is replaced during the

@brief the number of nesting levels an operation recurses into
Operations that walk a value (serializing, hashing, merging, ...) recurse once
Operations that walk a value (copying, comparing, serializing, hashing, merging,

per nesting level, which is fastest, but a value nested deeply enough would
exhaust the call stack. So they recurse only this many levels deep and finish
whatever lies below with an explicit stack. All of them share this limit.
Most of them pass the depth down as an argument. The copy constructor and the
comparison operators cannot, as their signatures are fixed, so they count it
in basic_json::nesting_depth() instead, a byte per thread; the limit must
therefore stay below 255.
