public double doubleValue()

    Returns the value of this MutableFloat as a double.

    Returns:
  - compareTo
```
public int compareTo(MutableFloat other)

    Compares this mutable to another in ascending order.
    
    Specified by:
    
    compareTo in interface Comparable<MutableFloat>
    
    Parameters:
    
    other - the other mutable to compare to, not null
    
    Returns:
    
    negative if this is less, zero if equal, positive if greater
  - equals
```
public boolean equals(Object obj)
```
    Compares this object against some other object. The result is true if and only if the argument is not null and is a Float object that represents a float that has the identical bit pattern to the bit pattern of the float represented by this object. For this purpose, two float values are considered to be the same if and only if the method Float.floatToIntBits(float)returns the same int value when applied to each.
    Note that in most cases, for two instances of class Float,f1 and f2, the value of f1.equals(f2) is true if and only if
    
    f1.floatValue() == f2.floatValue()
    
    also has the value true. However, there are two exceptions:
    
    If f1 and f2 both represent Float.NaN, then the equals method returns true, even though Float.NaN==Float.NaN has the value false.
    If f1 represents +0.0f while f2 represents -0.0f, or vice versa, the equal test has the value false, even though 0.0f==-0.0f has the value true.
    This definition allows hashtables to operate properly.
    Overrides:
    
    equals in class Object
    
    Parameters:
    
    obj - the object to compare with, null returns false
    
    Returns:
    
    true if the objects are the same; false otherwise.

public int hashCode()
```
    Returns a suitable hash code for this mutable.
    
    Overrides:
    
    hashCode in class Object
    
    Returns:
    
    a suitable hash code
  - toString
```
public String toString()
```
    Returns the String value of this mutable.
    
    Overrides:
    
    toString in class Object
    
    Returns:
