HP 30b Brochure page 4

The 100 memory locations used to store up to 50 pairs of statistics or cash flow data can be addressed
indirectly using a location stored in memory 0. If 5 is stored in memory 0, the key sequence
th
:$:y will store the value in X into the 6
position of the statistics data area, since it is
addressed starting with position 0. This allows for the use of a rather large data set and has already been
used to compute and store nearly 700 digits of PI on the HP 30b as shown in the Programming Examples
learning module.
And, of course, all the existing scientific functions (and other financial functions) are still present in the
HP 30b.
Conclusion. This is a good financial machine that addresses many wish-list items left unfulfilled from
the HP 20b. In many ways, this is the most powerful financial calculator HP has ever made. It is certain
to give fits to the financial calculator designers at a certain company near Dallas, since there are a large
number of empty spaces next to their models on any comparison chart. Now, HP, we're all still hoping
(and waiting) for a new low-end scientific model.
