These citiations refer to the decimal type. This type is still constrained
by the underlying hardware. For example,
type Decimal_Number is delta 0.001 digits 20;
will not compile under GNAT.
Dr. Beiber is correct in his suprise that Ada does not have a
straightforward approach to BCD. Of course, few languages
do have this. COBOL continues to be an easy approach to
solving business data processing problems that falls short in Ada,
C++, C, Java, and most other languages. Somehow, the
designers of these languages just never quite understood this
simple idea.
