Class LocaleNumericFormat

java.lang.Object
  quadbase.util.LocaleNumericFormat

All Implemented Interfaces:

IFormat

public class LocaleNumericFormat
extends java.lang.Object
implements IFormat

This class formats and parses numbers in a locale-specific way. Because it is a wrapper class of java.text.NumberFormat, it is not intended for displaying very large or very small numbers that require exponential notation. Please use quadbase.util.NumberFormat for these cases. This class cannot directly extand java.text.NumberFormat because java.text.NumberFormat is an abstract class. All formats implement quadbase.util.IFormat. Please use quadbase.util.IDataPointSet.setLabelFormat(int colIndex, IFormat format) to set the label format of a data column.
