Usage

From source file:de.jfachwert.math.PackedDecimal.java

/**
 * Liefert den uebergebenen String als {@link PackedDecimal} zurueck.
 * Diese Methode ist dem Konstruktor vorzuziehen, da fuer gaengige Zahlen
 * wie "0" oder "1" immer das gleiche Objekt zurueckgegeben wird.
 * <p>/*w  ww.  ja  v a2  s  .c  o  m*/
 * Im Gegensatz zum String-Konstruktor darf man hier auch 'null' als Wert
 * uebergeben. In diesem Fall wird dies in {@link #EMPTY} uebersetzt.
 * </p>
 * <p>
 * Die erzeugten PackedDecimals werden intern in einem "weak" Cache
 * abgelegt, damit bei gleichen Zahlen auch die gleichen PackedDecimals
 * zurueckgegeben werden. Dies dient vor allem zur Reduktion des
 * Speicherverbrauchs.
 * </p>
 *
 * @param zahl String aus Zahlen
 * @return Zahl als {@link PackedDecimal}
