As I understand this, these BigNumbers are used where precision matters
and performance
doesn't. Look at
http://java.sun.com/j2se/1.3.0/docs/api/java/math/BigInteger.html
and
http://java.sun.com/j2se/1.3.0/docs/api/java/math/BigDecimal.html
These could be useful if you are doing cryptogaraphy and want to do
exact calaculations on long numbers ( factor 10^128) or retain some
large
number of digits after a division.
What I don't understand is why BigDecimal isn't derived from BigInteger.
It looks like BigInteger is (really) a String and BigDecimal *is* a
BigInteger with a scale factor. Is there anyway to postpone division
( say, somekind of BigRational class)?
Do you have a link to something like " How to Represent Money (in a
Servlet, of course)" ?
I don't have any idea what the issues are. Presumably, control of
rounding in exchange
calculations would be one issue.
Thanks.
