accept() needs the value of a number only for a float whose exponent may reach the largest value. skip_digits() finds the end of the digits without the multiply-adds of accumulate_digits(), and once an 8-byte word fails the digit test, the remaining loop needs no bounds check: a non-digit is in that word. The value is computed afterwards for the rare floats that need it. accept() of canada.json: -16 % on Apple M1, -22 % with GCC 15 and -21 % with Clang 21 on x86-64; files with many numbers -9 to -15 %.
