ArrayVector<E extends Number>

static final class ArrayVector.Decimal
extends ArrayVector.Floats

A vector backed by an array of type float[] to be converted to double in a way that minimizes the errors when represented in base 10. This implementation should be used only when there is good reasons to believe that the float data where encoded in base 10 in the first place (for example in an ASCII file).
