```
public java.lang.Float toFloat()
```
    Gets this mutable as an instance of Float.

    a Float instance containing the value from this mutable, never null
  - equals
```
public boolean equals(java.lang.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 java.lang.Object
    
    Parameters:
    
    obj - the object to compare with, null returns false
    
    Returns:
    
    true if the objects are the same; false otherwise.

```
public int compareTo(MutableFloat other)
```

    Specified by:
    
    compareTo in interface java.lang.Comparable<MutableFloat>
    
    Parameters:
    
    other - the other mutable to compare to, not null
    
    Returns:
    
    negative if this is less, zero if equal, positive if greater

    Overrides:
    
    toString in class java.lang.Object

    the mutable value as a string
