C++ is an object-oriented programming language which gives a clear structure to programs and allows code to be reused, lowering development costs. C++ is portable and can be used to develop applications that can be adapted to multiple platforms. C++ is fun and easy to learn! Paradigms: Object-oriented programming Designed by: Bjarne Stroustrup

This listing was obtained by running apt list --installed | grep boost.
The code can be compiled with the provided makefile using the standard make
command.
If compiling the code manually, or integrating into a larger program, include the following flags:
FLAGS=-std=c++17 -fsanitize=address -fuse-ld=gold -Wall -MMD \
-fext-numeric-literals -lquadmath #-O3
Note that flag -fuse-ld=gold is only required on certain Ubuntu systems due
to a know bug with g++ 5.x.
If run without command line arguments, using
./precisionEstimate
the following usage message will be displayed.
Usage: ./precisionEstimate numExecs
If run using
./precisionEstimate 100000000
output simliar to
0 secs | 1.19209e-07
1 secs | 2.22045e-16
17 secs | 1.92593e-34
will be displayed. Note that the precision estimates will vary by architecture/system.
