-   If ENDPTR is not NULL, set *ENDPTR to point to the first byte beyond the

-   - In case of overflow, return ±HUGE_VAL or ±HUGE_VALL, respectively, and
-     set errno to ERANGE.
-   - In case of underflow, return a value very near to 0 and set errno to
-     ERANGE.
-   - If the string does not start with a number at all, return 0 (and recall
-     that if ENDPTR != NULL, *ENDPTR is set to NPTR), and maybe set errno to
-     EINVAL.
-   - In case of other error, return 0 and set errno, for example to ENOMEM.  */
