== DESCRIPTION:

'Uncertain' adds a Numeric class that encapsulates and handles numbers with uncertainty (e.g., 1.0 +/- 0.2).

== FEATURES/PROBLEMS:

* Properly performs math on uncertain numbers (except for trig functions)
* Plays well with 'ruby-units'... just create a unit like '1 +/- 0.1 mm'.unit

== SYNOPSIS:

Uncertain(1,0.1) #=> 1 +/- 0.1
1.to_uncertain(0.1) #=> 1 +/- 0.1

== REQUIREMENTS:

* 'ruby-units' is optional

== INSTALL:

* sudo gem install uncertain
