Shore - 10-20-2012 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 Re: New Blog: Factorials - Walter B - 10-20-2012 Just FYI, all factorials you mentioned in your blog may be calculated directly on a WP 34S in DBLON mode :-) Re: New Blog: Factorials - Paul Dale - 10-20-2012 More importantly, the 34S includes a Log Gamma function which effectively calculates the sum of the logarithms directly. - Pauli Re: New Blog: Factorials - Bart (UK) - 10-20-2012 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. Re: New Blog: Factorials - Gerson W. Barbosa - 10-20-2012 So does the HP-50g, but the wp 34S is more accurate: ```001 LBL A 002 INC X 003 LNGamma 004 # 010 005 LN 006 / 007 IP 008 RCL L 009 FP 010 10^x 011 END 111 A --> 1.76295255109 x<>y --> 180. ``` On the HP 50g, ```111 ENTER << 1. + LOGGAMMA 10. LN / DUP IP SWAP FP ALOG >> EVAL ``` will return ``` 180. 1.76295255248 ``` Gerson. Re: New Blog: Factorials - Eddie W. Shore - 10-21-2012 Quote: Do it on the 50G emulator, then "Save Object".

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. (no programs this time though) Edited: 23 Oct 2012, 9:28 a.m. Re: New Blog: Factorials - Eddie W. Shore - 10-21-2012 Learning the upgraded WP 34S on my list of things to do.
