toString

public String toString()
Description copied from class: Object
Suppressed: Returns a string representation of the object. In general, the toString method returns a string that "textually represents" this object. The result should be a concise but informative representation that is easy for a person to read. It is recommended that all subclasses override this method.

The toString method for class Object returns a string consisting of the name of the class of which the object is an instance, the at-sign character `@', and the unsigned hexadecimal representation of the hash code of the object. In other words, this method returns a string equal to the value of: 

 getClass().getName() + '@' + Integer.toHexString(hashCode())

Overrides:
toString in class Object
Returns:
a string representation of the object.

toJavaFormatString

public String toJavaFormatString()

readJavaFormatString

public static FloatingDecimal readJavaFormatString(String in)
 throws NumberFormatException
NumberFormatException

doubleValue

public double doubleValue()

floatValue

public float floatValue()
