The VDT mathematical library
============================
What is VDT?
------------
**VDT is a library of mathematical functions**, implemented in double and single
precision. The implementation is **fast** and with the aid of modern compilers
(e.g. gcc 4.7) vectorisable.
VDT exploits also Pade polynomials. A lot of ideas were inspired by the **cephes
math library** (by Stephen L. Moshier, moshier@na-net.ornl.gov) as well as
portions of actual code. The Cephes library can be found here:
http://www.netlib.org/cephes
Implemented functions
* log
* exp
* sincos
* sin
* cos
* tan
* asin
* acos
* atan
* atan2
* inverse sqrt
* inverse (faster than division, based on isqrt)
