s.
For sequences of the same dimension, the ordering is lexicographic.
Otherwise, lower dimensions are sorted before higher.
The dimensions compared can be limited; if this is done
ordinate dimensions above the limit will not be compared.
If different behaviour is required for comparing size, dimension, or coordinate values, any or all methods can be overridden.

compare
public static int compare(double a, double b) Compare twodouble
s, allowing for NaN values. NaN is treated as being less than any valid number.- Parameters:
a
- adouble
b
- adouble
- Returns:
- -1, 0, or 1 depending on whether a is less than, equal to or greater than b
