Subject ITC's java.math package contribution
Date Thu, 20 Apr 2006 19:51:31 GMT
Dear all,

on behalf of ITC I have updated our contribution of the package
java.math including some recent optimizations (HARMONY-199).  I think
it  would be interesting to compare our implementation with the one
donated by Intel (HARMONY-39).  In order to do that, it would be nice
to have a collection of applications were the package is used.

So far, we have tried both implementations with a realistic
application (RSA key generation) and our implementation turned out to
have a significantly better performance.

Another point is that we implemented the full 1.5 API functionality,
which in the case of BigDecimal amounts to having about twice as many
methods as in the 1.4.2 API.  This may have little significance now,
but it will definitely be important when Harmony moves to 1.5

Our implementation uses 1.5 syntax since the 1.5 API includes an Enum
(RoundingMode).
It should be easy to obtain a 1.4.2 implementation of the 1.4.2 API from it.

Some more information about our development can be found at
