|

* A collection of mathematical routines that strive to be better suited to
|
||||
* DSP than, e.g., those supplied by your C standard library.
|
||||
*
|
||||
* Such a goal is hopefully accomplished by:
|
||||
*
|
||||
* * being as branchless as reasonable/convenient;
|
||||
* * not handling uninteresting corner cases, such as invalid,
|
||||
* infinity, and NaN input values;
|
||||
* * returning approximated results (indicated in this documentation).
|
||||
* * not handling uninteresting corner cases, such as out-of-range,
|
||||
* NaN, and sometimes infinity input values (out-of-range and NaN inputs
|
||||
* are always considered invalid and lead to undefined behavior);
|
||||
* * returning approximated results (indicated in this documentation);
|
||||
* * making no distinction between `0.f` and `-0.f`.
|
||||
*
|
||||
* In practice they should guarantee fast and consistent performance, but
|
||||
* always do your own benchmarking.
