If the parameter ``se`` is not ``NULL`` the location it +references is also set. + + +Description +----------- + +:ref:`PR_strtod` converts the prefix of the input decimal string pointed to +by ``s00`` to a nearest double-precision floating point number. Ties are +broken by the IEEE round-even rule. The string is scanned up to the +first unrecognized character. If the value of ``se`` is not +(``char **``) ``NULL``, :ref:`PR_strtod` stores a pointer to the character +terminating the scan in ``*se``. If the answer would overflow, a +properly signed ``HUGE_VAL`` (infinity) is returned. If the answer would +underflow, a properly signed 0 is returned. In both cases, +``PR_GetError()`` returns the error code ``PR_RANGE_ERROR``. If no +number can be formed, ``se`` is set to ``s00``, and 0 is returned. -- cgit v1.2.3
