Example Program to calculate Factorial

[Gamo]

Dieter program for HP 25 version is very well done that even include ABS and INT. Very short and really simple easy to understand program so far.

I added the ABS steps to work for HP-12C and still the program steps is under 20 steps.

Code:


01  ENTER
02  x
03  SQR
04  INTG
05  1
06  X<>Y
07  X=0
08  GTO 14
09  x
10  LSTx
11  1
12  -
13  GTO 07
14  Roll Down
15  GTO 00
