Q: How do I change the number of decimal places the calculator
displays?
A: The procedure is described in “Decimal Places” on page 34.
Q: How do I clear all or portions of memory?
A:
C
clears the calculator line.
@c
clears the data lists or
variables accessible from the current menu. Erasing the entire contents
of memory is covered in “Erasing Continuous Memory” on page 229.
Q: Why am I getting the wrong answer using the TVM menu?
A: Be sure to enter a value for all five TVM variables, even if a value is
zero (as
FV is for a loan without a balloon). Clearing the variables
before starting (
@c
) accomplishes the same thing. Check the
appropriate payment mode (mortgages and loans are typically End
mode calculations), and specify the number of payments per year
(
). Also check that all figures for money paid out are
negative
(the cash-flow sign convention).
Q: Can I access the TVM menu functions from the Solver?
A: No, but you can do the same functions by copying the appropriate
financial formulas into the Solver. The formulas are given starting on
page 168.
Q: Can I access the data stored in my CFLO and SUM lists from the
Solver?
A: Yes. See “Accessing CFLO and SUM Lists from the Solver,” page
177.
Q: How do I indicate multiplication in an equation typed into the
Solver?
A: Use the multiplication key (
*
). You cannot use the letter
in
the ALPHA menu.
Q: What does an “E” in a number (for example, 2.51E
－13) mean?
A: Exponent of ten (for example, 2.51
x
10
-13
). Refer to “Scientific
Notation” on page 47.
Q: The calculator has displayed the message
. What should I do?
