New Blog: Factorials Eddie W. Shore Posting Freak Posts: 764 Threads: 118 Joined: Aug 2007 10-20-2012, 01:42 PM The might of the 50g is demonstrated. It think it is the first time I typed a 181 digit number. Program for the 39gii is included. Eddie Walter B Posting Freak Posts: 4,587 Threads: 105 Joined: Jul 2005 10-20-2012, 03:27 PM Just FYI, all factorials you mentioned in your blog may be calculated directly on a WP 34S in DBLON mode :-) Paul Dale Posting Freak Posts: 3,229 Threads: 42 Joined: Jul 2006 10-20-2012, 05:59 PM More importantly, the 34S includes a Log Gamma function which effectively calculates the sum of the logarithms directly. - Pauli Bart (UK) Posting Freak Posts: 850 Threads: 10 Joined: Mar 2009 10-20-2012, 06:17 PM Quote: It think it is the first time I typed a 181 digit number. Do it on the 50G emulator, then "Save Object". Run HPUserEdit, then import it with "File" -> "Import" and then you can copy the number. (You can also save it as a variable on the real 50G and copy it to a PC with the SD card, and import into HPUserEdit).Thanks for your blogs, they're always interesting. Gerson W.

LN / DUP IP SWAP FP ALOG >> EVAL ``` will return ``` 180. 1.76295255248 ``` Gerson. Eddie W.

Copying the number is a lot easier than typing the number out. Update: Bart, I have posted another entry rearding factorials, basically an introduction to factorials - inspired by my dad.
