:mrdocs:

Parse the specified `string` string as a 128 bit decimal floating‐ point value and return the result. The parsing is as specified for the `strtod128` function in section 9.6 of the ISO/EIC TR 24732 C Decimal Floating‐Point Technical Report, except that it is unspecified whether the NaNs returned are quiet or signaling. If `string` represents a value that absolute value exceeds the maximum value or is less than the smallest value supported by `ValueType128` type then store the value of the macro `ERANGE` into `errno` and return the value initialized to infinity or zero respectively with the same sign as specified in `string`. The behavior is undefined unless `input` represents a valid 128 bit decimal floating‐point number in scientific or fixed notation, and no unrelated characters precede (not even whitespace) that textual representation and a terminating null character immediately follows it. Note that this method does not guarantee the behavior of ISO/EIC TR 24732 C when parsing NaN because the AIX compiler intrinsics return a signaling NaN.
