Detailed Description

ERXUnitAwareDecimalFormat extends java.text.DecimalFormat to add an automatic unit conversion feature for the given unit. Convenient to display friendly values for file size, elaps time, etc.

Examples:

 import java.text.NumberFormat;
 import er.extensions.ERXUnitAwareDecimalFormat

 double smallValue = 123.0d;
 double largeValue = 1234567890.0d;
 NumberFormat formatter = new ERXUnitAwareDecimalFormat(ERXUnitAwareDecimalFormat.BYTE);
 formatter.setMaximumFractionDigits(2);

 // Will display "123 bytes"
 System.out.println(formatter.format(smallValue));

 // Will display "1.15 GB"
 System.out.println(formatter.format(largeValue));
