New material: doing maths in Java

The section on mathematical operations in Java has been expanded over the last few days to include some new material that will be useful to those writing maths-related applications in Java. Notable inclusions include:

• The section on the performance of java.util.Math methods has been expanded somewhat to include more information about the timing and implementation of certain operations.
• A new section on BigDecimal and BigInteger looks at how to manipulate arbitrarily large numbers (or numbers of arbitrary precision) in Java. We include an analysis of the performance of multiplication.

As usual, suggestions for improvements to this section or suggestions for new material are always welcome, either on this blog or on the Javamex forum.
