◆ parse_infnan()

from_chars_result fast_float::detail::parse_infnan	(	const char *	first,
		const char *	last,
		T &	value
	)

noexcept

Special case +inf, -inf, nan, infinity, -infinity. The case comparisons could be made much faster given that we know that the strings a null-free and fixed.

◆ power()

constexpr fastfloat_really_inline int32_t fast_float::detail::power ( int32_t q )

constexprnoexcept

For q in (0,350), we have that f = (((152170 + 65536) * q ) >> 16); is equal to floor(p) + q where p = log(5**q)/log(2) = q * log(5)/log(2)

For negative values of q in (-400,0), we have that f = (((152170 + 65536) * q ) >> 16); is equal to -ceil(p) + q where p = log(5**-q)/log(2) = -q * log(5)/log(2)
