The program opens with option "3" to compute other constants etc, but when I choose that it just goes to Pi, I can not find a way to compute the number "e"...???? What are the exact steps in choosing e to compute ?
Y-Cruncher's instructions are in the file called "Command Lines.txt" which is included in its zipfile. Look especially under the section heading "Custom Compute".
Note to everybody else:
Y-Cruncher is not a program for HP programmable calculators, but for Windows and Linux computers.
