Luc Maisonobe resolved MATH-412.
--------------------------------
Resolution: Fixed
Fixed in subversion tree as of r992696 for branch 2.X and as of r992697 for
trunk.
The Dfp class represent the high precision numbers, it implements our existing
Field interface and hence each instance is associated with a DfpField that
provides the constants at the required precision as well as factory methods.
This allowed to remove the compile-time constraint in the library. Users can
even use at the same time a field for 20 decimals digits precision and another
field for 100 digits precision. Dfp instances with different precision CANNOT
be mixed in the same computation (doing so creates a NaN).
A few utility methods have been added, like constructors from integral types,
isInfinite and isNaN methods, equal has been renamed to equals and its
signature changed to match the general Object method (a hashcode method has
been added too).
Thank you very much for this contribution.
