Re: Imposing dimensional consistency in business calc's Message #4 Posted by Palmer O. Hanson, Jr. on 10 Jan 2009, 11:05 p.m., in response to message #3 by Palmer O. Hanson, Jr.
Joerg Woerner translated some parts of the manual. Thank you, Joerg.
The problem from page 33 described at the top of this thread:
Example: What is the total amount of earned interests, if you invest DM 1000 for 3 years with an annual interest rate of 7% and yearly payment?
Enter:
C 1000 PV 7 I 3 N CMP FV
Display:
1255,043 total accrued value
Enter:
- DIS PV =
Display:
255.043, total of the earned interest
Please notice how the DIS key is used to use a previous entry.
To calculate the compounded interest, you have to subtract the daily value from the final result.
If you calculated FV, you simply have to press - DIS PV = and the calculation will be done in a logical order.
Description of the INT key from page 22:
INT Interest Amount key
This key is used in conjunction with the CMP key to calculate bank discounting and accrued interest
Description of the DIS key from page 23:
DIS Display kay
Recalls an entry to verify. Maybe used before the CMP key without interfering previous entries.
Comment 1: If you press DIS immediately after the CMP key, e.g. with CMP DIS PV, the previous entry will be displayed. To continue the calculation you HAVE to press CMP again.
Comment 2: In some cases the recall of previous entries is allowed after a calculation. Please refer to the example "aufgelaufener Zinseszinsbetrag" on page 34.
