stickyRound

float stickyRound(double dval)

toString

public String toString()

Description copied from class: Object

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()

appendTo

public void appendTo(Appendable buf)

readJavaFormatString

public static FloatingDecimal readJavaFormatString(String in)
                                            throws NumberFormatException

Throws:

NumberFormatException

doubleValue

public double doubleValue()

floatValue

public float floatValue()

parseHexString

static FloatingDecimal parseHexString(String s)

stripLeadingZeros

static String stripLeadingZeros(String s)

Return s with any leading zeros removed.

getHexDigit

static int getHexDigit(String s,
              int position)

Extract a hexadecimal digit from position position of string s.
