You can find a number of other formatting tools :

FreeHEP Java Library - ScientficFormat - this class comes with a library of classes developed for applications in High Energy Physics (HEP). It is a free and open source libarary. Package and class specifications can be found in the API documentation.

printf package - Henrik Bengtsson - provides formatting methods fprintf(), printf() and sprintf(), which follow their counterparts in C. Free for personal use.

printf for Java - this Java version of the C routine comes as shareware at sharkysoft.com.

Quantity Library - nanoTITAN - this free open source library provides various classes for dealing with physical quantities and also comes with some utilities. These include NumberFormatSI, ExponentialNotationSI, and ScientificNotationSI for scientific formatting.

International Components for Unicode for Java (ICU4J) - DecimalFormat - The earlier versions of Sun's java.text.DecimalFormat did not provide for scientific notation and some other desirable features, so IBM developed its own version.

Initially IBM provided this class in its own text package but they later donated the package to the open source ICU4J project, which provides a large number of tools for text handling.

The ICU4J, and the corresponding ICU4C for C/C++, is an open-source project that provides Java with internationalization and Unicode support classes that can be added to the JDK packages. (Unicode is used for the coding of all text in Java. We will discuss it in detail in a later chapter.)

The ICU4J set of packages can be downloaded for free but it is a multi-megabyte set of files. So it may not be worth the resources simply to obtain access its DecimalFormat class. A description of the DecimalFormat class is found at

and the specifications page in the API at
