Subject [jira] Created: (MATH-168) Suggestions For New Features On Math Module of Apache Commons

Suggestions For New Features On Math Module of Apache Commons
-------------------------------------------------------------

                 Key: MATH-168
                 URL: https://issues.apache.org/jira/browse/MATH-168
             Project: Commons Math
          Issue Type: New Feature
    Affects Versions: 1.1
            Reporter: Sunburned Surveyor
            Priority: Trivial


I would like to suggest a couple of additions to the Math module. I am currently working on
code for an alternative to the BigDecimal class that allows for precise mathematical calculations.
The PreciseNumber class and related classes allow for manipulation of digits in a floating
point number to be manipulated in a manner similar to characters in a String. It also allows
the fractional part and whole part of a number to be manipulated independently. The class
also stores information about precision, significant digits, and allows leading a trailing
zeros to be stored and manipulated.

I'd also like to see a number class representing a double between greater than zero but less
than 1. 

I also have been doing some work on classes to represent angles, bearings, azimuths, vectors,
and directions.

I know there is concern about bloating the commons libraries, so I understand if there is
no room for this code. :] I just wanted to follow up on a post I made to the commons mailing
list.
