  - getAsDouble
```
public double getAsDouble()
```
    Specified by:
    
    getAsDouble in interface java.util.function.DoubleSupplier
    
    Returns:
    
    the value.
  - hashCode
```
public int hashCode()
```
    Overrides:
    
    hashCode in class java.lang.Object
  - equals
```
public boolean equals(java.lang.Object other)

    Overrides:
    
    equals in class java.lang.Object
    
    Parameters:
    
    other - Object to test for equality with this instance.
    
    Returns:
    
    true if the objects are equal, false if other is null, not of the same type as this instance, or not equal to this instance.
