:mrdocs:

Parse the specified `string` string as a decimal floating‐point value and return the result, loading the specified `status` with a bit mask providing additional status information about the result. The supplied `*status` must be 0, and may be loaded with a bit mask of `k_STATUS_INEXACT`, `k_STATUS_UNDERFLOW`, and `k_STATUS_OVERFLOW` constants indicating wether the conversion from text inexact, underflowed, or overflowed (or some combination) respectively. 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. The behavior is undefined unless `input` represents a valid 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. The behavior is undefined unless `*status` is 0. 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. Also note that the intel decimal floating point library documents that inexact, underflow, and overflow are the possible floating point exceptions for this operation.
