Gilles commented on GEOMETRY-41:
--------------------------------
bq. "tolerance" was present in the original commons-math code
I'm sure it's necessary. ;-)
The example(s) would make it clearer for me how they are used to avoid
(in)accuracy problems.
And it would be a nice illustration of how to use the library (for beginners
like me).
bq. I use larger tolerances for the larger models
This is what makes me wonder whether the most common usage of
{{DoublePrecisionContext}} wouldn't rather be with *relative* tolerances.
Being able to fiddle with the two examples which you mentioned would be quite
useful for trying it out.

> The {{Vector?D}} classes should expose {{equals}} method overloads that allow
> a precision object from GEOMETRY-11 to be passed in to determine equality. I
> propose adding the following two methods:
> 1. {{boolean equals(Vector?D vec, DoublePrecisionContext precision)}}
> 2. {{boolean isZero(DoublePrecisionContext precision)}}
