MRMathCPP is a collection of very simple math routines very carefully implemented.
This library started as a way to render common constructs like
abs(x1-x2)<eps into more readable code like fc::near(x1, x2, eps).
Over time it grew to contain much more, but I’ve tried to keep the
focus on simple stuff like sgn and max4 that I use over and over
again across several code bases.

If you are using an IDE, then simply add the lib/ directory, or the
.hpp files, to your project. If you are using GCC/Clang on the
command line, then add the lib/ directory to your include path with
the -I compiler option. To use from CMake, see the file
IncludeMRMathCPPLib.cmake
at the root of the repository.
In your code you can include just the specific headers you need, or
include them all by with MRMathCPP.hpp.
HAVE FUN!
