1 The VDT mathematical library
2 ============================

4 What is VDT?
5 ------------
6 
7 **VDT is a library of mathematical functions**, implemented in double and single
8 precision. The implementation is **fast** and with the aid of modern compilers
9 (e.g. gcc 4.7) vectorisable.
10 
11 VDT exploits also Pade polynomials. A lot of ideas were inspired by the **cephes
12 math library** (by Stephen L. Moshier, moshier@na-net.ornl.gov) as well as
13 portions of actual code. The Cephes library can be found here:
