HP Forums - (12C) Fibonacci Numbers and Develop the Fibonacci sequence

Finding the Fibonacci Number by using program on HP 12C

Code:

01 ENTER

02 5

03 SQR

04 STO 1

05 ENTER

06   1

07   +

08   2

09   /

10   X<>Y

11   Y^X

12   RCL 1

13   /

14   Fix 0

15   GTO 00

Example: 12 R/S result 144

Result accuracy is best below n<39

For HP-12C Platinum in ALG mode.

Develop the Fibonacci sequence program.

---------------------------------------------

Procedure:

1 [R/S] [R/S] [R/S] ....... display Fibonacci Sequence

Remark: Must start from 1

--------------------------------------------

Example:

1 R/S 1
R/S 2
R/S 3
R/S 5
R/S 8
R/S ..........
--------------------------------------------
Program: ALG mode

Code:

[+] [X<>Y] [+] [LSTx] [=]

Remark:

To have this program keep on going automatically
Added [PSE] [GTO] 001
