<h2>Precision</h2>
|
|
Abacus uses a mathematical tool called Taylor Series to determine values
|
|
as accurate as the user desires. Of course, this comes with some
|
|
performance issues with larger numbers. However, Abacus has been
|
|
tested to generate the value of e correctly to a thousand digits.

<h2>Configurable and Customizable</h2>
|
|
The very first idea for Abacus was inspired by how difficult it was
|
|
to program a TI-84 calculator. Only two languages were available, TI-BASIC
|
|
and Assembly, the latter having virtually no documentation. Determined
|
|
to be better than a TI-84, Abacus implemented a plugin system that allows
|
|
users to easily create and add plugins written in the same programming
|
|
language as Abacus itself - Java. These plugins can access the full
|
|
power of the language, and implement their own ways of handling numbers,
|
|
as well as their own functions and even operators.<br><br>
|
|
Besides the ability to add plugins, Abacus also adds some general
|
|
options that can be used to make the user's experience more pleasant.
|
|
For instance, it allows for a computation limit to be set in order
|
|
to prevent excessively long evaluation: 8!!! is, for example, an expression
|
|
that even Wolfram Alpha doesn't compute accurately, and will never finish
|
|
on Abacus (it's simply too large). The computation limit will allow Abacus
|
|
to kill a computation if it takes too long. Support for user-definable
|
|
precision is also planned.

<h2>Built-in Documentation</h2>
|
|
Abacus plugins are given a mechanism to register documentation for
|
|
the functions that they provide. The Abacus GUI displays these
|
|
functions in a searchable list, allowing the user to read the parameters
|
|
that have to be supplied to each function, as well as learn about
|
|
its return value.<br><br>
|
|
The search finds functions not only by their names, but also by relevant
|
|
terms mentioned in the function's description, thus allowing related
|
|
functions to be displayed together.
