Numbers
This section begins with a discussion of the
Number
class in the
java.lang package,
its subclasses, and the
situations where you would use instantiations of these classes rather than the
primitive number types.
This section also presents the
PrintStream and
DecimalFormat
classes, which provide methods for writing formatted numerical output.
Finally, the
Math
class in java.lang is discussed. It contains mathematical functions
to complement the operators built into the language. This class has
methods for the trigonometric functions, exponential functions, and so forth.
