  1. Initial implementation for various functions. The CUDA side points to… 

    … the appropriate single or double-precision

function.

Switching is done based on HEMI_DEV_CODE preprocessor statement.

  1. fixed a couple typos in math.h, forgot to rename popcll to popcll fro… 

    …m brev.

Unsure if fma actually works or is just a infinite loop trap on host.

  3. Added working round() and lround() with simple algorithm for non-C++11 

    compilers.

Changed test makefile to look like examples'
Started test harness for math.h functions in hemi. Double-precision round() on the device is not passing an assert.

  4. Removed fma(), as it's new to C++11. When nvcc plays nice with -std=c… 

    …++11 in GCC-4.8 it can come back.

  3. Fixed indenting inside of #ifdef statements. 

    Removed hemi::fma for now, no c++11 support in nvcc (at least experimentally the compiler is choking on STL).

  2. Same problem as with atomics, was calling the wrong functions. Sorry … 

    …I didn't catch this the first time, this particular issue isn't something I have managed to come across before.
