public class MutableDouble extends Number implements Comparable<MutableDouble>, Mutable<Number>
double wrapper.
Note that as MutableDouble does not extend Double, it is not treated by String.format as a Double parameter.

public boolean equals(Object obj)
true if and only if the argument
is not null and is a Double object that represents a double that has the identical
bit pattern to the bit pattern of the double represented by this object. For this purpose, two
double values are considered to be the same if and only if the method
Double.doubleToLongBits(double)returns the same long value when applied to each.
Note that in most cases, for two instances of class Double,d1 and d2,
the value of d1.equals(d2) is true if and only if
d1.doubleValue() == d2.doubleValue()
also has the value true. However, there are two exceptions:
d1 and d2 both represent Double.NaN, then the
equals method returns true, even though Double.NaN==Double.NaN has
the value false.
d1 represents +0.0 while d2 represents -0.0,
or vice versa, the equal test has the value false, even though
+0.0==-0.0 has the value true. This allows hashtables to operate properly.
