* While the erfinv() function is exposed in the API, it will
* encounter floating-point precision issues if provided with
* input values greater than approx. +0.999999 or smaller than
* approx. -0.999999. If such extreme values are likely to arise
* during processing, it is highly recommended that programmers
* instead operate natively on the values q = 1.0 - p and/or
* qc = 1.0 + p, and pass the appropriate value (q or qc) directly
* to the erfcinv() function. This will ensure full use of
* available floating-point precision within these functions,
* which is otherwise lost if performing one of the above conversions
* (either implicitly within one of these functions, or explicitly
* by the programmer prior to invoking erfinv()).
