Continued Fraction
I've updated ContinuedFraction to use numerator a over denominator b.
This is consistent with the original source paper for the method.
Fraction
While looking at the fraction package it was very hard to compare
Fraction and BigFraction side-by-side. This is a problem as the two are
essentially the same using a different internal representation.
I also did a big arrangement of Fraction and BigFraction. The two had
diverged quite a bit in their internal method order and the javadoc. I
have updated them to be consistent. They should be easily compared
side-by-side and this will reduce maintenance burden when they are
updated together.
I copied the method order from Complex with changes as appropriate:
private constructors
factory constructors, including parse(String)
Properties:
zero(), one()
numerator(), denominator()
Computed properties:
signum
Conversions:
abs, negate, reciprocal
primitive values (double/float/int/longValue,etc)
Math:
Arithmetic
add,subtract,multiply,divide
Power functions
Standard object stuff:
toString(), compareTo, equals(), hashCode()
I spotted a bug in the Fraction.of(double, ...) constructors where there
was no validation of NaN or infinity so I have added this to Fraction
and BigFraction to throw an IllegalArgumentException.
