Reviewing Cash Flow Entries - HP 12c User Manual

64 Section 4: Additional Financial Functions
The complex mathematical characteristics of the IRR computation have an
additional ramification: Depending on the magnitudes and signs of the cash flows,
the computation of IRR may have a single answer, multiple answers, a negative
answer or no answer.
For additional information regarding L, refer to Appendix B. For an alternative
method of calculating IRR, refer to Section 13.

Reviewing Cash Flow Entries

To display a single cash flow amount, press :, then key in the number of
the register containing the cash flow amount to be displayed. Alternatively,
store the number of that cash flow amount (that is, the value of j for the CF
desired) in the n register, then press :gK.
To review all the cash flow amounts, press :g K repeatedly. This
displays the cash flow amounts in reverse order — that is, beginning with the
final cash flow and proceeding to CF
To display the number of times a cash flow amount occurs consecutively —
that is, to display the N
amount (that is, the value of j) in the n register, then press :ga.
To review all the cash flow amounts together with the number of times each
cash flow amount occurs consecutively (that is, to review each CF
pair), press :ga:gK repeatedly. This displays N
CF beginning with the final cash flow amount and proceeding to N
j
CF .

Neither L nor l change the number in the n register. However,
Note:
each time :gK is pressed, the number in the n register is decreased
by 1. If this is done, or if you manually change the number in the n register
in order to display a single N
n register to the total number of cash flow amounts originally entered (not
including the amount of the initial investment CF
and IRR calculations will give incorrect results; also, a review of cash flow
entries would begin with N
n register.
For example, to display the fifth cash flow amount and the number of times that
amount occurs consecutively:
