Examples of umontreal.iro.lecuyer.util.PrintfFormat

umontreal.iro.lecuyer.util.PrintfFormat
This class acts like a {@link StringBuffer} which defines new typesof append methods. It defines certain functionalities of the ANSI C printf function that also can be accessed through static methods. The information given here is strongly inspired from the man page of the C printf function.
Most methods of this class format numbers for the English US locale only. One can use the Java class {@link java.util.Formatter Formatter}for performing locale-independent formatting.
