- These tests test the total time taken to execute all of Boost.Math's test
- cases for these functions. In each case the best performing library gets
- a relative score of 1, with the total execution time given in brackets. The
- first three libraries listed are the various floating-point types provided
- by this library, while for comparison, two popular C++ front-ends to <a href="http://www.mpfr.org" target="_top">MPFR</a> ( <a href="http://math.berkeley.edu/~wilken/code/gmpfrxx/" target="_top">mpfr_class</a>
- and <a href="http://www.holoborodko.com/pavel/mpfr/" target="_top">mpreal</a>) are
