Constructor Detail

• BigDecimal

  public BigDecimal(BigInteger bigInt,
                    int scale)

  Constructor for BigDecimal. The value of the constructed BigDecimal equals bigInt / 10scale.

  Parameters:

  bigInt - The bigInt value parameter.

  scale - The scale of the constructed BigDecimal.

Method Detail

• getInstance

  public static BigDecimal getInstance(BigInteger value,
                                       int scale)

  Deprecated. This method is not part of the JDK's BigDecimal class and its presence is historical, as the first implementation of Codename One's BigDecimal class was ported from BouncyCastle, which is different than the JDK's BigDecimal class in that is optimizes binary arithmetic. The implementation of this method is counter-intuitive since it performs a bitwise left shift on value before scaling it. Use BigDecimal(com.codename1.util.BigInteger, int) instead if you just want to convert a BigInteger into a BigDecimal. Do not rely on this method as it will be removed in a future version of Codename One..
  Returns a BigDecimal with value value / 2scale / 10scale

  Parameters:

  value - The value of the BigDecimal to be created.

  scale - The scale of the BigDecimal to be created.

  Returns:

  The such created BigDecimal.

• 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

• equals

  public boolean equals(Object o)

  Description copied from class: Object
  Indicates whether some other object is "equal to" this one. The equals method implements an equivalence relation: It is reflexive: for any reference value x, x.equals(x) should return true. It is symmetric: for any reference values x and y, x.equals(y) should return true if and only if y.equals(x) returns true. It is transitive: for any reference values x, y, and z, if x.equals(y) returns true and y.equals(z) returns true, then x.equals(z) should return true. It is consistent: for any reference values x and y, multiple invocations of x.equals(y) consistently return true or consistently return false, provided no information used in equals comparisons on the object is modified. For any non-null reference value x, x.equals(null) should return false. The equals method for class Object implements the most discriminating possible equivalence relation on objects; that is, for any reference values x and y, this method returns true if and only if x and y refer to the same object (x==y has the value true).

  Overrides:

  equals in class Object

• hashCode

  public int hashCode()

  Description copied from class: Object
  Returns a hash code value for the object. This method is supported for the benefit of hashtables such as those provided by java.util.Hashtable. The general contract of hashCode is: Whenever it is invoked on the same object more than once during an execution of a Java application, the hashCode method must consistently return the same integer, provided no information used in equals comparisons on the object is modified. This integer need not remain consistent from one execution of an application to another execution of the same application. If two objects are equal according to the equals(Object) method, then calling the hashCode method on each of the two objects must produce the same integer result. It is not required that if two objects are unequal according to the equals(java.lang.Object) method, then calling the hashCode method on each of the two objects must produce distinct integer results. However, the programmer should be aware that producing distinct integer results for unequal objects may improve the performance of hashtables. As much as is reasonably practical, the hashCode method defined by class Object does return distinct integers for distinct objects. (This is typically implemented by converting the internal address of the object into an integer, but this implementation technique is not required by the JavaTM programming language.)

  Overrides:

  hashCode in class Object
