Class  Description 

Angle 
Angles as objects that know what units they are in, know how to do trigonometry without
needing help with unit conversion, and are therefore much less errorprone in lengthy calculations.
In java.lang.(Strict)Math you have to keep track of whether an angle is in degrees or radians when you use trigonometrical functions; the present class knows what to do, so you can forget about it! This should reduce the potential for errors of the degrees/radians kind. Rationale A continual refrain in Jean Meeus' excellent series of books on astronomical computation is the risk of errors due to the fact that angles are usually given in degrees but trigonometry requires radians. 
Gaussian 
Calculate values of the Gaussian curve.

Maths 
Static methods to do common mathematical calculations.

Maths.Statistics 
Just a record to hold public values.

RangeDouble 
Convenience record for holding a pair of doubles indicating the low and high ends of a range.

Util 
Miscellaneous useful static methods.

Enum  Description 

Angle.Format 
For formatting output values as strings.

Angle.Units 
Various units used for angles, and their symbols.
