Output helpers. mode 0 prints in positional notation when the scientific exponent satisfies -6 \le E \le 20, mode 1 in scientific notation unless E = 0, and mode 2 (for radii) in positional notation when -3 \le E \le 5. The digit functions write the digits of |x| with trailing zeros stripped and set t to the exponent of the last digit, returning the number of digits; _decimal_write_number writes (-1)^{\mathit{negative}}\,\mathit{digits} \cdot 10^t without a null terminator and returns the number of characters, and _decimal_write_number_bound bounds that number.
