Programs for the Sharp EL-5500 III

[Eddie W. Shore]

Programs:
Euclid Algorithm
Binomial Expansion
Days Between Dates
Complex Power (a + bi)^n
Error Function Approximation
Simpson's Rule
Dancing Star Demo

I really like the EL-5500 III. It is lightweight and BASIC programming.

The EL-5500 III is the US version of the PC-1403.
You may be interested by the Sharp PC-1403 entry points for matrix operations to be able to use them in BASIC programs. They have been published by Hrast on the previous hpmuseum forum:

• http://www.hpmuseum.org/cgi-sys/cgiwrap/...792#111281
• http://www.hpmuseum.org/cgi-sys/cgiwrap/...792#111389

It would be nice to confirm that these entry points are the same on the EL-5500 III.

Cool calculator and great programs!

I've implemented keystroke programming on a custom calculator project and am wondering how difficult it would be to implement a programming language like BASIC.

Eddie, I do not understand how the NPV program is supposed to work. Please help me here, this is the code on your website:

Code:

2  PAUSE “NET PRESEN VALUE”
4  CLEAR    // clears all the variables
6  INPUT “CF0:”; N, “RATE:”; I
8  J = 1
10 INPUT “FLOW:”; F, “FREQ:”; K
12 FOR L=1 TO K: N = N + F/(1 + I/100)^J: J = J+1
14 NEXT L
16 INPUT “MORE=1: “; L   // enter 1 to enter more cash flows, anything else to end entry
18 PRINT USING “#############.##”; “NPV: “; N
20 END

As far as I can tell the program will sum up the discounted first K cash flows in line 12/14. Then the user is prompted with "MORE" so that second, third etc. cash flow and its frequency can be entered. For another CF the user is supposed to enter "1", or anything else to quit. But look at line 16/18: the program does not process the user input L at all. Instead it prints the NPV (for the first CF only) and quits.

I'd say there is a line missing here:

Code:

17 IF L=1 GOTO 10

Or have I overlooked something here?

It always depends on the number of features you want, it can be really simple if you do a minimal implementation, have a look at uBASIC.

Do any of the other Sharp models have matrix ops?

[Didier Lachieze]

The Sharp PC-1475 has also matrix operations.

Thanks Sylvain.
