    passedVal - the object being compared with the current object
    
    Returns:
    
    -1 if the current object is less than the parameter, zero if the current object equals the parameter, +1 if the current object is larger than the parameter. NOTE: Due to the lack of precision in comparing floating point values, in cases where the two values are NEARLY equal, this method will return 0.
  - equals
```
public boolean equals(java.lang.Object other)
```
    Checks if the current object is equal to the parameter.
    
    Overrides:

public boolean isZero()
```
    Checks if the current object is equal to 0.
    
    Returns:
    
    true if the current object is equal to 0, false otherwise. NOTE: Due to the lack of precision in comparing floating point values, in cases where the value is NEARLY 0, this method will return true.
