[section:realworld Floating-Point Real World Tests]
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. Times are shown for both single threaded runs and concurrent execution - the latter
increases contension inside new/delete.
