"""Reliable Comparison of Floating Point Numbers.
Comparisons of floating point numbers are problematic due to errors
associated with the binary representation of decimal numbers. Despite being
aware of these problems, people still use numerical methods that fail to
account for these and other rounding errors (this pitfall is the first to
be highlighted in Circle 1 of Burns (2012) 'The R Inferno'
<https://www.burns-stat.com/pages/Tutor/R_inferno.pdf>). This package
provides new relational operators useful for performing floating point
number comparisons with a set tolerance."""
