Write the specified floating point `value` into the character buffer starting a the specified `first` and ending at the specified `last`, `last` not included. Use the {Default Floating Point Format}. Return the address one past the last character (lowest order digit or last digit of the exponent) written on success, or `0` on failure. The only reason for failure is when the range `[ first, last )]` is not large enough to contain the result. The written result is to begin at `first` with leftover room following the return value. The behavior is undefined unless `first <= last`. Note that these functions do *not* null‐terminate the result.
